Thank you for your testing, boothy.
Your CPU has ~37% lower frequency than mine, but only ~18% lower FPS rate, meaning yours is performing better per Mhz - thats not what I get if I compare with stats from the unofficial LFS benchmark site.
I think I'll give up on this, because I'm not understanding any of it now. The GPU drivers are shit (many ppl are complaining about GTX 295 drivers), and I can see the performance in ACDsee and Photoshop is "random" - but random in a way that it's either lacking in same fashion always or über smooth.
The OpenGL settings in PS CS4 have VSync enabled (looks smoother when panning), but quite often it drops to 30 clean. Not 20, not 35-40. It's either 30 or 60.
I'm still interested in more ppl doing
this test though, as more tests would make it easier to see the bigger picture regarding performance across different systems.
