Well im back for more... :wahoo: 

so... What you Ladies and Gentlemen think...

I have a ATI 5830... if I get a ATI 5970. I could use crossfire... total 4320 Stream Processing Units...hmmm

or should I go for ATI 6990 which has newer technology but only 3072 Stream Processors, of course my ATI 5830 will be unusable... no crossfire...?

More about : ati 6990 5970 5830

Whats your native?
What cpu/ psu do you have?
5970 5830 wont be worth it.

well the Double Precision Compute Power
the 5970 get up to 928 GFLOPS
while the 6990 1.27 TFLOPs

not much of a difference that I see there..

Who said it's not worth it ? yes it does ? what would be the problem at all ?
@ OP just ensure that you overclock the slowest Core, & memory clock to match up the higher one. For eg. if the 5970 is 730 MHz and 5830 is 800 Mhz, OC the 5970 to match the 5830 and same thing for the memory clock.

If HD 5970 is costlier than HD 6990 then you can buy 6990, it is more improved version for their DX 11 with better tessellation. So in the games like Metro and other DirectX games where HD 5970 sucked big time HD 6990 actually performed very well so going with the new technology is better in my view.

Yes, technically it should be better than HD 6990 if you just do as i said to match both cards so that no one is lagging the other. There's no a lot of benchmarks for HD 5970 TriFire but so far till now i saw HD 5850 with HD 5970 in TriFire and they are doing pretty good better than HD 6990

Well, looking at the prices on ebay the HD 6990 is $150-200+ over the HD 5970... both HD 5K and 6k series are DX11 capable and no much difference between them, the power of the HD 6k series would be in the more transistors, core & memory clock... that's all
A 5870 is doing much better than HD 6850/70 and very close to a HD 6950
The HD 6K series were equipped with 2 GB of VRAM to get a great support of Eyefinity besides it has a better scaling in CF than 5K, run much better quite and cooler.

I'd get two 6950's 2GB in crossfire instead of a 6990. Cheaper and better overclocking--unless you're planning on Quad Crossfire sometime.

I haven't seen enough benchies of assymetrical crossfire to recommend the 5830 + 5970. I feel like there's a lot of options you have though that are cheaper if all you're looking for is a big bump in performance from the 5830. What resolution do you play at? How many monitors?

And by the way 5970 is already dual card so mixing another single card for crossfire is quite a new thing that i haven't heard, so its totally up to you whether you want HD 6990 which is better in terms of performance and performs better in DX 11 games or you can go with 6950's 2GB in crossfire as mentioned above this post.

I'm not sure what information you were intended to convey with that benchmark post--that your monitor is 1680x1050? If that's what you want to tell us, then I can tell you that a single Radeon 6950 1GB can pretty much max out any game at that resolution. All the stuff you're suggesting is ridiculous overkill and not many people have info on it.

+1
and you'll need to OC your CPU to the limits if you want to Triple Fire, but Again a single GPU such as HD 6970 will be overkill for this resolution.

Even if you go with the 5970, I wouldn't 3 way it with the 5830. If it was a 5850 maybe, a 5870 for sure, but by downscaling the 5970 to be effectively two 5830's as opposed to slightly underclocked 5870's you'll be giving up as much performance as you'd gain wit a third card. (Remember 3 way doesn't scale as well as 2 way)

The 6990 will have better Xfire scaling than the 5970, and way better than the 5970 + 5830, and will give you the best raw performance. But if you want to save some cash buy a 5970 and sell your 5830.

I, like the others fail to see the reason for the massive output of money for a 22" resolution. This is silly, you simply don't need an HD 6990. If you read the "best video cards for the money" article you would see what people mean about "beyond reason."
It is simply not logical to spend that kind of money for driving a small monitor like that. Even with a triple monitor setup, an HD 6970 would be fine.

Crossfire with an HD 5830 is likewise not advisable as you'd be limited by the slower card. The 5830 has never been a favorite of enthusiasts, its not really close to the 5850 in performance and overpriced to boot.

Wait...so you're saying you have three 22" monitors? Can somebody provide some clarification on using 3 monitors with eyefinity Radeons. Do the screens need to be Display Port? If so, then I guess he can always crossfire instead.

If you game on a single 1680x1050 (size doesn't matter, just resolution), then a single Radeon 6950 1GB will meet all of your needs VERY well. Sell your 5830, get one of those, and you'll have $400 more in your pocket than you were intending to. I suggest you wait for November sales to buy.

Although the Phenom II x4 955 isn't the best CPU out there, so long as it can handle the game in the first place, it could handle crossfire. You can do that down the road. Just make sure it's OC'd.

PSU: Ultra x4 1050W? Wow...that's a nice PSU. I'd have just picked up a Corsair TX750 and saved $150 then bought a 5870. In fact, I'd still try to sell it and pick up something cheaper and then have more money in my pocket.

oh yes....
but at with a 5830 at 5040x1050 games lag...
and then if you throw FRAPS on top of that......

that why im asking 5830+5970 or a 6990?

For newer games, like Deus Ex: Human Revolution, you'll want all 4 cores and an overclock. I can show you some benchmarks of the bottlenecking (they're on Tom's Hardware).

Oh, I definitely and not suggesting triple monitors on a 5830. But triple on dual 6950 2GB's should work well.

What you should do is just pick up another 5830 and Crossfire them. It would cost you about 105 or maybe cheaper with rebates, This seems like the only reasonable thing to do at the moment. I would be a good match for your resolution.
No move you can make right now for 100 bucks will give you a better gaming experience.

Yeah, I guess a second 5830 is a viable option. I just hate the whole castrated 5850 thing about the 5830. I prefer the idea of dropping that card altogether, but it wouldn't be the most cost effective choice.

A 5970 and 6990 are both dual GPU cards. Using 1 card by itself you are already using crossfire, just as an all in one card. Therefore adding a 5830 to it would 3 way crossfire.

Regardless, what everyone else is saying is true. Unless you are going to be using multiple monitors then both are overkill.

tri crossfire wouldnt work to well between the 5970 and the 5830 as their gpus arent identical the 5830 would take longer to render each third frame than each gpu in the 5970 would take

crossfire only works well between identical cards, if you can afford it sell the 5830 and buy 2 6970's/580's for ultimate power

A 5870 and 5830 in crossfire would be the exact same as 2x 5830 in crossfire because the cards operate at the speed of the slowest card in the setup. So you could get a 5830, 5850, or 5870 and it would function as a 5830 regardless.

Again though, by the time you factor in scaleing, crossfire 5830's will only be slightly ahead of a single 5870, and likely perform very close to a single 6970 depending on the title. (5xx0 series cards don't scale as well in crossfire as the 69x0 series cards do)

Getting a second 5830 is not anyone's preferred recommendation--largely because 5000 series cards don't scale that well in crossfire, but also because people kind of hate the 5830's flaws. However, it is the most cost effective solution IF you don't sell your 5830.

I think you should try to get the single 6970 for $203, since it's regularly $300 and try to sell the 5830 for $90 or so.

October 22, 2011 1:11:24 PM

Three monitor setup? You'll need more than two 5830's. I don't know if a signle GTX 570 could quite handle it (not close to high settings on a lot of games) and it's a well established fact that a 6970 outperforms the 570 at extreme resolutions--although Hawx 2 will still favor the GeForces. But if you're playing a bunch of games and not just Hawx 2, then a 6970 will go further on 5040x1050.

But really the only way you play on all three with decent settings is dual 6950 2GB's or 6970's.
