I have a Intel Core i5 2500K with a P8Z68-v Pro motherboard that supports 2 PCI-E 3.0 slots as well as other 2.0 slots and such but I was just wondering is for gaming wise would a SLI setup of GTX 560Ti's(2x1GB) or a single EVGA GTX580 3GB graphics card would give me a better setup? Will be mostly for games and both setups cost around the same, am also open to a stronger ATI crossfire setup if anyone knows of any that would be more compatable with my motherboard/i5 2500k processor. Thanks and hope everyone has a great weekend!
Cheers

Get a 7950.

It's more powerful than the 580, and if you overclock it will probably be more powerful than the 560ti SLI setup as well. It will use less power, have none of the drawbacks of a multi-GPU setup, etc... for $450 it's a great buy right now.

As a 560ti SLI user I gotta say its an awesome set up and beats the 580 hands down.
The only thing tho is I'm limited to it as I can not add another if I wish to get more performance in the future , the 580 3gb is a good choice as you can also add another later and have a seriously fast gaming system , another suggestion is you could also consider a 7950, which is also a great card and can be xfired later too.
Comes down to personal choice , the 560ti SLI is a great and affordable option but you are limited in the future with them as to upgrading.

Whatever you do, don't buy a GTX 580... it has literally no advantages over a 7950 right now.

ESPECIALLY don't get the 580 3GB... it costs as much as the Radeon 7970 and is much slower...

Indeed.

The 3GB 580 is retarded. There is virtually no difference between it and the 1.5GB version...but the price.

It's really only useful for when someone is running a multi-display configuration, where the extra v-ram comes in handy - but even that's debatable.

get the 7950 if you want a good single card with less power draw/heat and not have to deal with multicard setup problems with drivers and microstuddering, get the 560tis for more raw performance.

Keep in mind the 560tis will draw almost 2x the power as the 7950 and thats all converted into heat somehow.

I would wait for the Nvidia 600 series to come out before pulling the trigger. The stats that have been proposed sound promising and you could get more out of a single card. I have seen a 2.5GB 570 in action and was shocked how well it handled the load. If you need to make a decision now, that's the card I would pick. 2 of those SLI'd would be destructive but I think the 600 Series models will be worth waiting for.

Skip the hype, look at the numbers........Using Guru3D game test suite......

One 580 = 616 FPS (76 cents per frame)
Two 560's = 862 fps (48 cents per frame)
One 7950 = 603 fps (75 cents per frame)
One 7970 = 675 fps (81 cents per frame)


February 10, 2012 8:27:33 PM

id get a 7950 over a 580 but 2 560 ti's are probly better than either one

either buy a 7950 or wait for kelper2 if you realy want a NVIDIA GPU. Their is no reason to buy 2x 560ti or a 580 for now.

This post ignores overclocking potential (which is going to be much higher on a 7950 or 7970 compared to SLI'd 560ti cards). Overclocked, the 7950 will approach the 560ti setup and the 7970 will beat it in most things.

The hassle of SLI is not worth the slight performance gains IMO. My recommendation stands as the 7950.

what real games were used for this? sli doesn't scale that well normally in games.
February 10, 2012 9:54:07 PM

An overclocked 7970 will easily beat the 560ti SLI setup in 3dmark11, which scales incredibly well with SLI...

Jack's post is very misleading.
February 10, 2012 10:29:18 PM

Ok so the one that is a common interest interest to people with the same gaming builds as me would be the:

XFX Radeon HD 7970 OC Black Edition 1000MHZ 3GB 5.7GHZ GDDR5 DL-DVI HDMI 2XMINIDP PCI-E Video Card $570


February 10, 2012 10:31:31 PM

If you can get the 7970 black edition for $570, go for it. Where in the world did you find that card in stock for $570?

BTW, when I say "overclocked 7970", I just mean any 7970 that you overclock yourself (seems that like 90% of 7970s can reach at least 1125/1575, usually without any voltage increases).

February 10, 2012 10:58:54 PM

How about we take a look at the real information behind your claims of performance:

"On some games, GK104 will handily trounce a 7970, on others, it will probably lose to a Pitcairn."

Source --> http://semiaccurate.com/2012/02/01/physics-hardware-mak...

The point is - there is not enough information out there on Kepler to influence purchasing decisions right now.

Playing the "wait 6 months and then company (x) will release a graphics card that stomps graphics card (y)" is a stupid game, because you could just flip the companies in 6 months. Some information indicates that the high end GTX 6xx series card won't even see the light of day till the end of this calendar year. Nobody has a clue.

Purchasing decisions should be made on available information and options at the time of purchase.
February 11, 2012 1:39:11 AM

I agree I'm not waiting longer than I have to for an unreleased card, considering there is plenty options out there that would work for 5 years or so.. Oh by the way that price on the black edition 7970 was a canadian website I'm assuming that's a taxes not included price heh. I did some research on peoples posts and think I'm going to go with a 7970 probably.. since it's a nice 3GB card that runs on pci-e 3.0 and is Quad SLI/crossfire adaptable. By no means would I ever quad Crossfire but crossfire 7970's down the road might be some searious power. I noticed the 7950's are just under ratings of 7970. Anyone know if the 7950 is a more stable card and not heat the system as much? Thanks all for the great advice, since it's my first build I have this site constantly in my safari browser on my phone for help :) ) a big thumbs up to the site providers fir their hard work!
February 11, 2012 1:49:21 AM

There's not too much difference between the 7950 and 7970 in terms of heat - neither is a super hot card (esp. if you get one with a custom cooler).

The 7950 will probably be a bit cooler, just since its clocks are lower. Clock for clock, however, there really isn't any meaningful difference between the two.

Post a screenshot of your scores then and show us.
February 11, 2012 12:05:02 PM

I think 2 560's is the best. For example the evga 560 ti ftw has 2 560 ti gpu's on one card and has better performance than one 588, so if you go two separate 560's it would be way better than the 580.

My SLi'd 560Ti's score higher than that so they must have been doing something wrong. :lol: 
February 11, 2012 2:11:05 PM

Hard to compare P scores because of the massive difference between your CPU and mine... X scores would provide a more accurate comparison of graphics muscle.

What was your graphics subscore? That would be the closest possible comparison in the P subset.

Even if your SLI'd 560ti setup scores higher than my 7970, it's certainly not going to be by a 10% margin like that (your X score would have to be ~3600!)

So your P score wouldn't be lower if you dropped your OC on that CPU?
February 11, 2012 2:47:20 PM

P score is much more heavily weighted than X score towards physics (ie CPU) performance.

Your 2600K is VASTLY superior to my phenom. Of course my score would be lower if I dropped my OC. Just like your P score would be much lower if you had an inferior CPU...

So What your saying then is performance wise on a Intel Core i5 2500K OC system, when setup right an SLI setup of GTX 560Ti's can out-perform an OC 7970? Im not going with Intel i7 system since the i5 2500K is better for gaming and thats what I want.. I've seen the threads about the overclocked i7 but thats more for video editing and such.

I would say so and so would 3D Mark '11, if you go by the P score.

No... he's ignoring the facts. His system scores higher on P score because his CPU is much better than mine (or the CPU that guru3d was using for their 560ti SLI / 7970 review chart I linked to earlier).

His graphics subscore is going to be lower than a 7970. In other words, his system would score even higher if he had a 7970 instead of 560ti SLI.

The best way to look at this is to also look at X scores in 3dmark11, which is almost entirely weighted on GPU performance. In this area, a 7970 beats 560 ti SLI, and an OC'd 7970 beats it pretty handily.

Here's a couple more benchies that put the X score of 560ti SLI around 2600-2800. Stock 7970s are benched I believe in the 2700-2900 range and OCd score in the 3200-3500 range depending on how high a clock you can get.

http://www.tweaktown.com/reviews/3813/palit_geforce_gtx...
http://www.xbitlabs.com/articles/graphics/display/gefor...

A 2500k (or 2600k) + 560ti SLI will beat a lesser CPU + 7970 in any CPU-limited game, but in any GPU limited setup, the 7970 + weaker CPU will win. Also, this assumes 90-100% scaling on the SLI, which does not always come through in games. 3dmark11 makes a good point of comparison because it scales almost 100% with multi GPU setups.


:EDIT: It is worth mentioning that the 560ti SLI is a better value than the 7970 in terms of performance. However, it is weaker in overall performance and I personally can't stand all the potential hassles that come with multi-GPU setups.

February 11, 2012 4:54:01 PM

A first time builder of a gaming rig might have troubles setting up the SLI it seems? That's a good point to take in since my old system was a highly outdated pentium 4.. The one SLI setup I was referring to was the GTX 560Ti 2win setup which is already configured to plug and play I believe. And games scaling to dual GPU setups is a good point since it will be older games my machine focuses on until I get into other games.
Main games I will be playing out of the gate is Everquest2 and maybe WoW. I'm heavily into MMORPG's least I was until my old system couldn't handle them lol.

I've been running SLi rigs since 2004 and have always found it very easy to set up and live with, I don't play MMORPG's though so I can't say whether SLi works in those titles or not but either way I would stay away from dual GPU cards.

From my original post:
"Here's my scores. Bear in mind that my Phenom limits the P score noticeably. "

But thanks for ignoring that part and accusing me of "backtracking". I'm aware that my P scores are low because of my CPU. I'm not sure why you imply that your GPU is the source of the difference (especially when other links with that GPU setup + a weaker CPU don't even get near P9000+).

Let's take CPU out of the mix, shall we? AND we can ignore the lousy CPU that whoever was doing guru3d reviews was using which killed the P scores there.

How about a pure search of 3dmark11 P score results? 560ti SLI on a 2600K (like yourself) vs HD 7970 on a 2600K:

560ti SLI (top scores around P10K) --> http://3dmark.com/search?resultTypeId=232&linkedDisplay...
