which card would suit this build best

Hi,

I'm purchasing components for a new computer, and I was curious which video would go best with the setup I want. I mainly play games on 2x Samsung 226BW's at 1850x1080(I think that's it). I don't mind settings not at full, for better fps. This is purely for playing games.

The main components I am purchasing are:

IP35 Pro LGA 775
Q6600
G-Skill 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1000 (PC2 8000)
RC-690
PC Power & Cooling Silencer 610 EPS 12V

I had been leaning towards an 8800 GTS G92, but I wanted to see if there were any suggestions. Also, if the 8800 GTS G92 is the way to go, which manufacturer would be best to go with, and why?

Thanks in advance for any input you might have.
