Dual HD 7950's or new GPU ?

Hello guys ,
Before we start off, heres my rig -
Intel i5-3570K
ASUS P8Z77 V LE PLUS
XFX HD 7950 Core Edition ( single ATM )
Corsair XMS3 4GB ( upgrading to 12 GB soon )
SeaSonic X 850W
CM HAF XB ( great airflow , 120x3 and 80x2 Fans )
WD 500GB Blue

Just today I got a great news , The GTX 770 is available in some close stores ( Finally ) Also I have money now , and was TBH planning to get a second HD 7950 , before the GTX 770 was coming out , I know a CF HD 7950 beats GTX 770 , 780 , and HD 7970. But the micro stutter and vidoe issues bother me. AMD isn't so interested in clearing these issues. So if I convince my dad to allow to sell the HD 7950 , and I save some money , Should I try for a HD 7970GE , GTX 770 or maybe a GTX 780. If I save all of my pocketmoney , 6k every month , then it goes like this -
GTX 770 -
35K ( approx ) =
17K for HD 7950
18K ( 3 months pocketmoney )

If my dad doesn't agree , Then should I CorssFire , it with the 7950 ? I want to get on ultra on 1080p with 50FPS+ ( buying monitor soon ) Or should I CrossFire it with a HD 7970 ( If yes , does anyone know a compatible GPU ?

Why are you CFing - My current HD 7950 isn't satisfying just yet. I am getting 45 on ultimate in Tomb Raider , So I wonder how I can play Last Light and other power demanding games on Ultra. Or should I wait for AMD to get drivers and by the time get a H80i ( wanna OC that i5-3570K ) and the RAM ?

I'd highly recommend the GTX770. What monitor are you gonna buy?

Fair enough! Well grab an IPS panel display if you can - any IPS will be far better quality than a TN panel.

I wouldn't worry too much. I can show you an 8ms panel giving faster response than a 6ms if you want! It's not a true measure of responsiveness at all - it's a useless number like the dynamic contrast ratios they quote. If you want real, measured numbers for contrast ratio, input lag etc then you need professional reviews like tftcentral.co.uk. They also do high-speed photography of motion on the screens so you can see zoomed up how much trails/blur there is. My monitor is slower than this one and it games really nicely. You can only see trails on it if you deliberately look for them.

Okay , but what about the GPU , on the other thread , one guy is recommending to wait for a driver release by AMD and then decide , the other is telling to sell that HD 7950 and opt for a GTX 770. What do you think ?
Also if the response time isn't that important , Okay I got it , I am buying that Dell S2240L. Or should I get 24inch ( personal preference though ) I want to game on 1080p on ultra or very high and get 50FPS+ , is the HD 7950 CF enough ? I also want it to last for 2 years ( later on I will use it on med-high if necessary )

Well 24"ers are generally pretty expensive. I buy 23"ers because that extra inch is expensive! If you can find one at a price you're happy with, it'll likely be 1920x1200 instead of 1920x1080. As for GPU, I'd definitely say the GTX770. It's almost always best to get a single powerful GPU. I've done Crossfire (and a single dual-GPU card) and it was crap. Best thing is one card. Second best is SLI. Worst is Crossfire. AMD said back in October 2012 that they were fixing Crossfire. I wouldn't hold your breath!

There are plenty of people with crossfire setups that love it. I recenty bought a sapphire 7950 and I'm considering getting a second one.
I played Metro last light on this card and it actually performed really well even at stock. I ran the game on Very high (max) settings with MSAA and Tessellation turned off. Like you, I hate not being at 60fps during gameplay but for the most part of the game I was at or near 60fps. The performance was even better when I raised the core to 1100mhz and power to 20%.

The GTX 770 and Radeon 7970 are definitely faster than a 7950 but I doubt they will make such a huge difference. I've seen benchmarks and gameplay where an overclocked 7950 was on par with and sometimes even beats a gtx 770 at stock. Just yesterday I was over my friends house and he has the same rig as me the only difference being is that he has a GTX 680 and he was playing Metro 2033. I saw his FPS and went home and played the same level and I was getting higher FPS on my 7950.

I can't vouch for crossfire as I have not tried it yet myself and I am also waiting for feedback on that new driver. If the issues are resolved more or less I will probably order another 7950 because I'm fairly certain I'll be able to play practically any game at a solid 60fps with two of these. A GTX 770 or Radeon 7970 may net you a small boost in performance over a 7950 and they may last a little while longer in terms of future proofing but they are over 100 dollars more expensive. I may end up selling the 7950 and ordering two GTX 770s but I doubt it. I'll most likely order another sapphire 7950 and be happy for a few years.

I see , but do you think your friend had underclocked the GPU for some reasons ? I mean the 7970 was some 4-5 FPS behind the GTX 680. Wondering , nothing else. Also do you think I can get a second HD 7950 from a different brand , version , with same clocks and memory ? ( mine's a XFX HD 7950 Core edition )

The performance difference is considerable - over 30% at stock. That's enough to turn 30fps into 40fps (or 60fps into 80fps if you prefer). 7950s do usually overclock well (though it's pure luck if you get one with a lot of headroom - seen many threads of people disappointed they're not overclocking as high as expected).

It's silly to compare any overclocked card to any stock card though. If you can overclock a 7950 you can overclock a GTX770 (or GTX680 etc). So you should either compare stock to stock or overclocked to overclocked. I compare stock speed because like I say, overclocking headroom varies hugely - there's just no guarantee. There's a reason people call it the "silicon lottery".

Also, does anyone know how effective Crossfired 7950s would be at different clock speeds? I know with SLI it's not even possible to mix clockspeeds. I think Crossfire allows it, but mixing slower and faster cards can actually drag down performance (and it'll certainly make it harder for Crossfire to avoid microstutter). So if you do Crossfire them, you should ideally clock them both at the same speed. Would be interesting to see if any benchmarking has been done on this.

http://www.youtube.com/watch?v=CQAbBU43mpo maybe this guy doesn't know what he's talking about but that sure doesn't seem like a 30% increase to me. Also I don't know how accurate GPUBOSS is but for FarCry3 the GTX 770 does get 18fps more than the 7950. But for some reason farcry3 gets lower fps on the 7970/7950 cards compared to the nvidia.

Will do. I suspect there would be load balancing issues that would increase stutter if clockspeeds weren't matched. I might email it to Chris as an interesting idea for an article. Or could open a thread for opinions / experiences? Would need that frame time software (FCAT?) ideally.

Anyway my point is this... Considering the performance I'm getting from my one 7950 I believe adding another one would shred any game that is compatible (assuming crossfire works properly). That being said, you will definitely get more FPS with 2 GTX 770s or 2 Radeon 7970s. However, going by what I've seen and been told I don't believe it would be a 30% increase.

Ah well if that is accurate and trustworthy then it's a 24% increase in performance. But hey the 770 is at a firm $400 and you can get a sapphire 7950 for $250 :)

I'd like to believe that two of any of these cards would be overkill for any game but I know that high MSAA can bring a GPU to its knees. I'm content with 2X MSAA though.

Also the GTX 760 is a great card at an amazing price I would have probably got it over the 7950 if it was out at the time. I got my 7950 two weeks prior to the release of the 700 series lol

Nope, it doesn't work like that :-) Google "mathematical reciprocal". 66% * 150% (50% over the whole) = 100% (0.66 * 1.5 in your calculator) - you can't simply add and subtract. You can either say 7950 is 76% as fast or GTX770 is 31% faster. I'm not a maths teacher but I'll try and explain further if you don't understand. And it's absolutely trustable - read the test method page if you doubt it. All latest drivers and an average across 18 games. You won't get a more accurate result than that.

And don't use MSAA - use injectSMAA for SSAA-grade antialiasing with almost no performance impact. Just remember to run as administrator or the game will probably crash.

And GTX760 is indeed awesome - I'd have bought one myself if they hadn't taken so long to release it. Really the only reason to go higher is for maxing Crysis 3 and maybe Metro 2033.

Agreed with both of you. I would have opted for a GTX 760 too. But my HD 7950 is 3 and a half month old already. And I finished 3 games as well , :p  BTW I will most likely be getting the same HD 7950.

Yea I guess that 30% extra performance is what you're getting for your $150 bucks more with the 770 but why are the linus benchmarks so close together though? Also if anybody knows a good chart for crossfire/sli performance please share thanks :)

About maxing Crysis 3 and Metro 2033. I get really good fps in both of those games at max settings with my 7950. I have to turn down 2 settings in FarCry 3 (terrain and water) to get it to run well and even then my fps dips into the low 40s in many areas.

July 17, 2013 12:49:46 PM

Well I have a more powerful card than you do and mine only just barely managed Crysis 3 maxed at 1080p. Anything slower and I'd have started dropping settings. I haven't played Far Cry 3 yet - doesn't really appeal. I didn't much like Far Cry 2 - took a billion bullets to kill an enemy and it was never-ending, just dragged on and on... my brother is playing FC3 and says it's the same. I'll probably play it eventually though. That 80s style DLC does look like fun :-) Currently blasting through Max Payne 3. Nothing like as good as MP2 but I'll probably finish it anyway.

Oh and all the regulars on here says Linus Tech Tips is a load of crap. I asked why, and they said he overclocks cards he likes and runs others at stock, uses different driver versions etc. Basically not fair testing. Techpowerup is absolutely brilliant for fair testing. Also avoid Anandtech - they don't OC selectively like Linus but they do mix up driver versions (they reuse old results from previous reviews to save time). Anandtech have even mixed up numbers from different test setups (different CPU etc). They've been doing it for years and it's really unprofessional. TPU actually put in the time and make the effort to fair test. Even though there's old cards in their reviews, they're all freshly tested with the latest drivers. Plus average performance ratings generated from 18 games! Nobody else can beat that (though Tech Spot is pretty good for large number of games tested).

Linus and AnandTech were already in my list of "Stay Away from them" review list. I have even heard that Linus is mostly paid , and AnandTech is just crap ( realised that from the name :p  )

Weird, Crysis 3 runs really well at max on my 7950. FarCry 3 is actually pretty good. Doesn't take a million bullets to kill an enemy even on hard mode. There are lots of "side quests" if you're into that. I tend to stick to the main story line which is why I hated the elder scrolls games they had piss poor main story line (and very short at that) and tons of "side quests" but the story line in FarCry 3 is actually alright and it's fun to play. You can buy new and better weapons, upgrade them and even change their appearance.

LOL about Anandtech :-D Yeah it's really disappointing they're so lazy and don't put in the time/effort because interms of their technical understanding of the hardware, they're an incredibly smart bunch. If you just want to learn about the technology behind SSDs etc, it's a good site for that. Just not for any accurate benchmarking.

Pavel, possibly you just have lower standards than I do for smoothness? I couldn't put a number on my gameplay because I don't bother with framerate counters - I just adjust settings until I'm happy the gameplay is smooth and responsive. For me, it was an acceptable level, but with any lower hardware (such as a 7950) I would have used high instead of very high. I do like to feel I'm seeing the game at its best but I know that I'll notice the difference in performance more than I'll notice the difference in settings, so I'll generally make performance my top priority.

I actually never bothered with Elder Scrolls games, mainly because I know they'll take over my life. Also because I know they're glitchy as hell and I've already gone through all that with Fallout 3 and New Vegas (didn't finish either - just too damned long). Now that you mention weapon progression, I did really enjoy that in FC2. It's the main thing that kept me playing. So I probably will play FC3 eventually, but other stuff I want to play first (Hitman Absolution, Call of Juarez Gunslinger, Assassin's Creed 3, Serious Sam 3, I Am Alive, maybe the Wolfenstein and Rise of the Triad remakes).

Naw I don't enjoy a game if it's not totally smooth. If the game isn't running smooth with max settings I'll turn down one or two settings that make almost no visible difference but give me a big boost in fps and responsiveness. Every game I play is at 60fps for the most part with the exception of a few areas where it dips down a bit. By the way what is your GPU?

EVGA GTX670 FTW. It's factory-overclocked to stock GTX680 performance, though I think they pushed it a bit too hard for a stock cooler. And you must be gaming at really low res? Tom's has your card not performing that great in Crysis 3 maxed. It can't average 40fps at 1080p, let alone 60fps!

Yea lol I don't know what that's all about and I've seen that page "Can it run it" for Crysis 3 it showed my card at 34fps. But believe me when I tell you the game ran flawlessly for me. All settings at very high with shadows at high and 2XSSAA had me at a constant 60fps. The fps only dipped into the 40s one time for about 5 seconds on the last part of the last boss which looked amazing by the way (coolest looking boss I've ever seen). I also play Crysis 3 multiplayer and it's really smooth.

When I first turned on Metro Last light I was disappointed with the performance but after turning off MSAA and Tessellation that game also ran pretty much flawlessly and looked amazing. My friend and I tested Metro 2033 on both of our rigs. All specs are identical except the GPUs. I have the 7950 and he has the 680. At stock mine was getting more fps and when we overclocked them both I still got more fps. Granted it was a 4-5 fps difference but still. And Metro is a game that caters to nvidia.

Tomb Raider is another game that ran really well and looked great. I had to turn off that Tressfx crap because it would lag me out when the camera zoomed in on her hair during cutscenes.

I play at 1080p on a 24 inch dell monitor.

I've asked this exact same question by the way. Here are the anwers I got http://www.tomshardware.com/answers/id-1712761/radeon-7...

And the 670 is in the same place as the 7950 on the GPU Hierarchy chart. In the best cards for the money page it does mention that the 7950 gets performance somewhere in between a 7870 (some special version of the card) and a 670 so the 670 should get better performance but I doubt it's much different.

I want 2 770s but I would have to sell the 7950 for about 200 bucks and add 600 bucks to get them. Or I can just get another 7950 for 250 bucks and I'm pretty sure that 2 of them in tandem would shred any game for a year or two considering my one 7950 is almost doing that already and in some cases is doing that.
