PhysX dedicated GPU...

[Bat123Man]

GTA4 benchmark :

Avg of 3 runs with following enabled :
1440*900
Texture Low
Vsync Off
Water High
Shadows High
Anisotropic 2X

SLI at 2.133 MHz = 25.49 FPS
SLI at 3.000 MHz = 30.15 FPS

Not bad, that's a pretty substantial improvement for a simple overclock. 4.66 FPS improvement represents a gain of 18.2%. Nice.

I guess you are not getting huge differences because of your gpus already being a limitation. I mean I had way larger gains on my E8500 Core 2 duo at 1920x1080 with a gtx260 than what you are showing. in games like GTA 4 and BC 2 I would get almost twice the framerate at 3.8 as I did at 2.0. you only showed a 20% performance increase with a 40% frequency increase and at just 1440x900. I showed over 80% increase with a 90% oc in GTA 4 even at 1920x1080.

Yeah, my cards only have 320 MBs on them. Your GTX260 has 896 MB, nearly 3 times the amount of vRAM I am dealing with. I suspect that is probably the single biggest contributor to my bottleneck. Most recent games deal in very large textures, and 320MB is far too little (I have seen min specs of 1GB cards). I have been looking at the hilarious 2560 MB GTX 570 to see if I can swing it. It's only 80 bucks more for 2.5 GB instead of the 1.2, although I certainly don't need that much vram I would rather have it than the 80 bucks. Plus it is likely to give me a fair amount of longevity with that much RAM.

yeah at 1024x768 and even 800x600 I hit a vram wall on playable settings in many games with my slow 8600gt 256mb. 320mb would not cut it at 1280 and above on settings the 8800gts could otherwise handle. even when it came out several years ago, the 320mb 8800gts model was already a bit sketchy from a vram standpoint.

The 320mb 8800gts model was already a bit sketchy from a vram standpoint.

Hahahahaha! Yeah, don't I know it. At the time, most cards were 256MB, and I had a chance to go for an extra 64 MB if I went for the 8800 GTS with 320MB. It is such an odd amount of RAM, games expect 256, 512, or 1024, but never 320. But it had more RAM! So of course I went for it. And I have to tell you I was completely psyched about 2 years ago when someone put up the identical card on eBay for only 50 bucks. It gave me about a 60% boost in FPS running in SLI, which got me to today. So I'll probably go for that 2560MB 570GTX, and see what kind of performance I get with my overclocked 3.0 GHz dual-core 6420. If I can turn on the advanced features in GTAIV at 1920*1080 and still get 40 FPS or so, I'll be happy as a clam.

many settings impact the cpu not just the gpu especially in GTA 4. you have basically zero chance of averaging 40 fps in that game with settings anywhere near cranked using an E6420 at 3.0. http://www.pcgameshardware.com/aid,...ead-of-Core-2-Quad-in-CPU-benchmarks/Reviews/

GTAIV is one of the most configurable games out there as well where you can dynamically adjust the draw distance to fill up your cards VRAM no matter how much you have. Some games may optimize for 512MB or 1GB but with GTAIV you can crank up the settings to fill up any amount of VRAM whether it be 256, 320, 512, 768, 896 or 1GB.
