2560x1600 FXAA Overclock Comparison
On this page we are going to look at performance in our games at 2560x1600 on a 30" display. We are using the FXAA setting in the games supported instead of MSAA, FXAA on average uses 2-3% of performance. With FXAA enabled, the framebuffer is not tapped as much as it would be with MSAA enabled, as FXAA is a shader based algorithm and thus stresses GPU shader performance. However, 2560x1600 in of itself can be a demanding resolution as it stands, when you turn all in-game quality settings to the highest settings as we have done.
The GALAXY GeForce GTX 660 Ti GC 3GB video card had no problems running any of these games at 2560x1600 with the highest in-game settings with FXAA. Performance, as you will see with the card overclocked, is playable in each game on the GALAXY GTX 660 Ti GC 3GB. We will compare that video card's highest overclock with the highest overclock we achieved with an ASUS GeForce GTX 670 DirectCU II TOP video card and an XFX Radeon HD 7950 Black Edition. Both video cards have achieved above average overclocks, and thus represent the best GTX 670 and HD 7950 performance you can get from overclocking. All data below is apples-to-apples.

ImageShack.us Our GALAXY GeForce GTX 660 Ti GC 3GB video card when overclocked to its maximum potential holds itself up well to an overclocked GTX 670 and overclocked HD 7950 in this game. It seems our overclocked HD 7950 is actually the fastest card in this game when we overclocked it to near 1.2GHz, we are averaging 63 FPS. The overclocked GTX 670 is right behind it at 59.6 FPS and then the overclocked GALAXY GTX 660 Ti is behind that at only a 3 FPS average loss of 56.4 FPS.
We were surprised to see the GALAXY GTX 660 Ti so close to the GTX 670's overclocked performance, both are very close and would be impossible to tell apart in actual gaming. Also to our surprise was the lead the HD 7950 has when it is overclocked in this game. Worth mentioning we have see AMD performance increase with drivers recently released.

ImageShack.us n Max Payne 3 performance is close between the overclocked GTX 670 and overclocked HD 7950, literally 1 FPS average separates them. The GALAXY GTX 660 Ti GC overclocked video card is the slowest, if you consider averaging 68 FPS slow and only a 5 FPS average difference from the overclocked GTX 670.
Batman Arkham City

ImageShack.us Tables turn in Batman and the overclocked GTX 670 takes the lead, and then second to that is the GALAXY GTX 660 Ti GC overclocked video card. In this game, the HD 7950 overclocked video card takes the back seat. It seems the HD 7950 has a lot of trouble with tessellation performance in this game, even with the video card highly overclocked.

GALAXY GTX 660 Ti GC OC vs. OC GTX 670 & HD 7950
We take the GALAXY GeForce GTX 660 Ti GC 3GB video card, overclock it to its maximum potential and compare it to an overclocked GTX 670 and overclocked HD 7950, both of which represent high-end overclocks. Will the GTX 660 Ti crumble, or will it stand up to an overclocked GTX 670 and HD 7950?

Skyrim
In Skyrim we were impressed how well the HD 7950 did when we overclocked it to this level. It received a large performance increase from stock HD 7950 clock speeds and came out on top in this game delivering 16% better performance than the overclocked GTX 670 with 8X MSAA at 2560x1600 in this game. The overclocked GTX 670 was 17% faster than the GALAXY GTX 660 Ti GC overclocked video card. Note, while the differences were large in this game, this setting was still playable on each video card tested here at these clock speeds.
