If you play other games, I would suggest the dual 460's. I am very happy with my 480 though, and I installed Left 4 Dead 2 recently, and the 480 runs it flawlessly at maximum AA settings without a hitch. A 460 SLI setup is supposed to be a bit better performing than a single 480 with other games, but a 460 SLI setup might be a bit more stable than a single 480 with the BP=0 tweak.

thanks for the info. I'm getting some price quotes today for the 480s.....and also a pair of 460s to compare.-feng

If you go the dual 460s route let us know how it works in FSX.  I may buy another one also.Thanksjja

I ended up ordering 3 GTX 480s for triple SLI :) Now shopping for 3 screens to try out the super-wide thing (after watching youtube videos w/ 3 screens....i'm sold!...especially for driving games).I'll post some fps reviews when i get them in about a week. -feng
