Early results are 1483 shader, so that's about 742 on the core. I have not found my max on my memory yet and was content to test @ a flat 1850 (3700). I'll update when I do. I tested both cards in my i7 rig so the CPU and memory would be identical.
STALKER: CoP

I was actually angry when I was done running this bench. The 470 is much more fluid in this bench than the 5870 and certainly moreso than triple HD 5870 Crossfire that puts up better than
twice its averages. I will stress again, that's with AA. The ATi card(s) are equally fluid
sans AA. FPS does not reflect this, you have to see it to believe it.
This OCed 470 feels darn solid and fluid, an OCed 480 must really be something. If you can afford the 480, get that sucker.
