I have AMD x6 1055T and GTX 480 w/ 260.99whql(default 3D setting) and you look my results (1680x1050, 1920x1080, 1920x1200 and 2560x1600*) ->
http://www.esenthel.com/?id=benchmark/sci_fi1920x1200: Win 7 x64 - 85 fps
XP-SP3 x86 - 93 fps
I got 54.744 fps at my 1st time - 2560x1600* and good luck because my CRT monitor 21" Samsung 1100P Plus works 2560x1600@60Hz.

* - I worked this resolution this on XP but I can't work on Win7 x64.

NOTICE: Tilde is not equal to ~ but yes '\' because I can't benchmark while I pressed key '~'.
