Alright so I'm in a bit of a pickle here, i can either buy a EVGA GTX 570 (350$) or a HD 5970 from ATi for the same price but slightly used, from what i can see in the benchmarks the 5970 outperforms the 570 in most benchmarks even the 580 (sometimes) now i know that the 5970 is over 2 years old and the 570 is still fresh form last year.

I plan to play BF3 @ 1920x1080p High/Ultra and most high end games (crysis 2, Metro 2033, Skyrim)

what are your suggestions?

Computer:
Processor: AMD 965 @ 3.8 ghzx4
RAM: 4 GIGS @ 1600 MHZ DD3
PSU: 750 Watts

Thanks for that well constructed and very helpful response, but unfortunately i cannot do any Crossfire or SLI , i should have added that in the OP sorry :(
 
Well As long as the HD 5970 is only compared with GTX 580, you can't put it in comparison with GTX 570.
HD 5970 > GTX 570. Argument is done here.
Regarding the 2 GTX 560 TI in SLI, yes they perform pretty good but you might also consider HD 6950s in CF, AMD HD 6K series scales better than nVidia GTX 5K series.
 
@ 384 bit, that depends on your definition of CPU bottleneck.
In most cases, a CPU bottleneck occurs in case of the CPU is not handling the game or you have excess of GPU power.
If i7 2600K is achieving higher FPS than 955BE...this is another thing to discuss.

taking mal recommendation "more FPS doesn't mean the best card" i agree with this 100% unless OP has a 3D monitor :)

A bottleneck will limit the amount a card can do, not lower it.

get the HD 5970, your processor will hardly bottleneck it at 3.8Ghz, and if you ever want to upgrade to Eyefinity you will have the GPU and CPU power to do so.

Also, which 750W PSU do you have exactly?

More likely you had a defective chip than a bottleneck, your in a very low percentage of people where a Phenom II 955 @4Ghz blocks any single card, let alone dual card.

@ OP : Here's some benches http://www.anandtech.com/bench/Product/297?vs=306

The HD 5970 only draws ~20 more watts, but shoots out massive performance increases in demanding games at high resolutions.

EDIT : If a new processor gets you an %100 increase, it's obvious something was wrong with the Phenom.

Anyway, in that one game that somehow got you a %100 increase, and you are in the 3 people who have done this and proved it.

What has this got to do with what GPU OP needs to buy, CPU bottleneck isn't a reason, what if he wants to upgrade his CPU later on, he'll be wishing he kept the HD 5970.

Bottleneck...... :hello:
Test systems with a 5970 are overclocked core i7's or higher.
Let me tell you that a 980 BE is doing better than the I7 in the test suites.
And as i told you achieving higher FPS ccan be gained from several ways, an i7 CPU with HD 5970 achieving 100 FPS and X6 with 5970 achieving 90 FPS can't be included under the term "Bottleneck" at all.

My last OT post.
5970 is a dual gpu card yes.
The game i tested with my 480 was black ops which was awful with the amd cpu.
So if my findings were bad with a high calibre single gpu, what is a 5970 going to do?
This was my point but i gather you missed it.


It's a single, console ported, horribly buggy game that had to get multiple performance patches.
I thought about it, but deemed it unworthy as it hardly made sense to use this as a basis for your point.
