How I tested Drivers
I left the drivers on both the cards to their default settings. Only Vsync was turned off.
ATI driver is by default set to maximum quality. Same is not the case with Nvidia forceware which is by default to 1 notch down from the highest quality settings. But it was left alone. Overclocking
Overclocking was done using Rivatuner 2.06.
On ATI its very simple, just Core and memory speeds are changed.
On 8800GT and GTS however there is shader clock as well and with this version of Rivatuner you can change that in Sync with the core or separately. I set it to overclock in sync with the core clock. This is what matters more. overclocking shader clock benefits the 8800GT and GTS more than anything else.
3Dmark 2006
3DMark 2006 was updated with latest patch and was allowed to run at its default settings. This is purely synthetic benchmark so I did not spend too much time on this.
Prey
This is another very popular game widely used for GPU benchmarking. To benchmark this I used HardwareOC benchmarking tool. Game was set to max details @ 1680x1050 resolution. Guru3D demo built into the benchmarking tool was used. 4XAA and 16XAF settings was used.
Serious Sam 2
Another very popular arcade game. Huge open areas, HDR, plenty of action on screen makes it ideal game to benchmark the cards. Framerate is usually very high without the Anti Aliasing and default auto detech game settings. But with max details 4XAA and 16XAF the game can be really hard on even modern GPUs.
Game was updated to latest 2.070 patch.
HardwareOC benchmarking tool proved to be little annoying with this game as the settings inputed in the tool did not stick when the game actually ran resulting in very high framerate. So I used built in demos of the game with the Fraps.
World In Conflict
This is highly anticipated new game release which bring out the real eyecandy and DX10 really does make difference in this game. DX10 mode is very hard on the GPU and you will find that out in the results. Game was unplayable on 8800GTS @ stock speeds.
I used max details in both DX9 and DX10 mode and games built in benchmarking tool.
Unreal Tournament 3 Demo
This is probably what most of you will be interested in. The demo is simply stunning and shows what to expect from this game. The gameplay was simply amazing and even though low resolution textures were used for ground the game was simply great looking and ran very well.
All in game settings were set to max. No AA was used as its not supported in the demo and there is no way to force it on the 2900Pro. So to keep the gamefield even it was left out.
Game was ran at 1680x1050. This is one of the few games which is really using the multi core CPUs. All 4 cores were partially loaded during the gameplay.
Enough talks, lets head to the numbers.
