AMD Radeon 6970 vs GTX 570, and what psu would you recommend?

If you are going to be running at higher than 1080p resolution, then the 6970 might be a good idea because of the extra V-ram. The 570 is a better bang for buck in my opinion. For a power supply, you should probably go with a high quality 650 watt or greater, such as Corsair.

6970 performs better on higher resolutions.
A good 600W+ PSU can handle both cards fine

1920x1080 ..? which one would perform better ..?

the GTX 570 is 2% slower overall than the 6970 on 1920x1200 http://www.techpowerup.com/reviews/HIS/Radeon_HD_6970/2...

to save some money you could get a 6950 2gb and unlock it to a 6970 but its a little more hassle.

if not then get the 6970 because of the 2gb vram.

6970 is better cause it has more RAM + it runs better on higher resolutions

here are your two best options for your power requirements:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE: $85

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
- CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE: $100 ($90 after rebate)

you can go with either card for great game-play at 1080p in terms of performance... your choice should be based on the different 'pluses' each company has -> for Nvidia mainly: Cuda + better 3D support... and for AMD mainly the Eyefinity option that they have

I noticed that the 6970 is the same price as a 570 now on Newegg.com I would go with the 6970 then if you're playing higher than 1080p resolution. I like Physx in games like Mafia 2, so I would personally go with the 570.

isnt it like 6950<560<570<6970 in performance?

6950 is a little faster than GTX 560

no, it's more like: 560<6950<570<6970... then: 6970<580<6990

sry that's what i meant , misstyped  

I always thought the 570 was better than the 6970 ..i know the 6970 is more powerful on benchmarks ..but doesn't the 570 outperform the 6970 at 1080p res ..?

nope

hmm ..maybe I should turn my attention to the 580 then ..i want better than 6970 performance ..  

I know you wanted to keep PhysX out of the discussion, but if there is little separating the cards, maybe that tips the balance in favor of the Nvidia card. You do play at least one PhysX game.

if you're willing to spend ~$500 on a 580... you may as well consider then 2 x 6950 2GB cards in Crossfire... you can get each one for $250 after rebates... and on top of that flash their BIOS's to the 6970 class card (make sure you choose a 6950 2GB based on the reference design) and you'll get way better performance than the 580 spending the same amount...

any (two) of these:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
- HIS H695F2G2M Radeon HD 6950 2GB

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
- MSI R6950-2PM2D2GD5 Radeon HD 6950 2GB

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
- GIGABYTE GV-R695D5-2GD-B Radeon HD 6950 2GB

2 x 6950 2GB cards is now getting to 6990 class performance (and for lots cheaper)

where do you come from Doppleganger I am Craig Harrison?

yes ..I think you've told me about Physx before ..I also play UT3 ..forgot ..
I wanted to leave it out cause it tilts the scales in favor of nvidia ..although there are so few actual physx titles ..anyways ..a 6970 can run metro at 45 frames ..and ut3 at over 200 ..so physx isn't that important ..

what exactly did you try to say ..? what's Doppler ganger ..?

But the difference isn't much.(overall)
Also no AMD fan here,I've always posted unbiased recommendations.

wouldn't an OCd 570 outdo a 580 ..?

can I OC a 6970 to do the same?

you can OC 6970 almost to performance of 580

so ..the 570 OCs better than the 6970 ..?
OCd 570>OCd 6970 ..?

no

6970=OCed 570 (more or less)

When overclocking, here is what Guru3d.com found:

570: +9% overclock to 800 mhz
6970: +7 % overclock to 950 mhz

CODMW2 @ 1920x1600 (stock/O.C.)
570: 148 fps/161 fps = +8%
6970: 140 fps/147 fps = +5%

BFBC2
570: 56 fps/64 fps = +9%
6970: 56 fps/60 fps = +7%

http://www.guru3d.com/article/radeon-6950-6970-review/2...

thatäs performance, and in normal performance 6970 is better

http://www.hardwarecanucks.com/forum/hardware-canucks-r...

one question, what does Physx allow you to do? like increase the performance or the picture quality?

physx offloads the calculation of in game physx to the GPU ..physx is a technology developed by the Physx corporation which was acquired by nvidia ..it makes the body motions and movements projectile trajectories, etc all look better ..

okay ..so then the 6970 is better than the 570 at 1920x1080 ..and can OC as well as a 570 too ..? plus the extra vram is a bonus ..

Yes^
Though I can't comment on the OC'ng potential but I think it'll do just fine

I don't understand ..why did you think you couldn't comment ..?

and anyways ..basically the 6970 is a better choice than the 570 because of the extra ram ..i mean I'm not so sure how much Physx actually helps ..?

ohh ..sorry ..thought you said "thought I couldn't" ..

I can't comment because i don't have 6970   The best thing is just to get it and play with the settings in order to achieve a good OC'ng result
As for PhysX,well it helps in few title currently(with the cost of lower FPS though)

yeah ..like metro and ut3 ..two games I play ..but I can pass on physx ..guess ill get a 6970 ..that extra ram seems a bonus ..especially in a year or two ..

In UT3 with PhysX enabled, vehicles explode into bits of debris, aircraft rain down parts when destroyed, body parts go flying in a big splat when you frag someone, flak bounces off walls, etc. I play UT3 frequently, and the extra particle effects are actually a big part of the visuals. It adds more fun to the gameplay. Honestly, I personally wouldn't get a card without PhysX, because I play PhysX games and know the difference it can make. Even if I don't use it, it's always nice to have, just in case.

This is a good chart to see how the GTX 570 and 6970 compare in various games. To read the chart, it is showing how a 6970 performs percentagewise in comparison to the GTX 570. The games that favor the 6970 have bars on the positive right-hand side of the center line, and games that favor the GTX 570 have negative bars on the left-hand side (you can click on the graphic for a more readable version):

ahhrgh ..!!! can someone tell me straight up ..which ones better at performance ..?????
according to Mattos list sure looks like look like I should be thinking bout a 570

the 6970 is better overall in performance on your resolution and the 2GB of VRAM is a big plus. http://www.techpowerup.com/reviews/HIS/Radeon_HD_6970/2...

hmm ..do you think Physx is anything of a plus in getting a 570 ..
matto would you reccomend a 6970, you've helped me out b4 ..?

I think I made my preference clear, and personally, I think the performance leans towards the GTX 570, especially at your resolution. 2 GB of VRAM is only going to help at the absolute highest resolution, which you don't play. There are plenty of charts on this page to support that the GTX 570 outperforms the 6970 at your resolution, while doing it quieter and cooler. But granted, it's close.

But if everything else is the same, then to tip the scales, I would look at performance in the games you personally play. Check the charts again, and don't forget you have at least two favorites that are PhysX games.

yeah ..I noticed ..but the others seem to favor the 6970 ..I'm going to do some more checking up ..  

+1 ^ what 'matto17secs' said... the 570 is the better choice out of the two in terms of raw performance average with your resolution (the 6970 will shine over the 570 @ 2560 / multiple-monitor setups mainly)

most people are going to recommend you the 6970 because most people here are huge AMD fans... these two cards are pretty close... but the 570 is better suited for you specifically
