For running twin monitors, I'd say any GPU will do. Personally, if you've got that kind of budget, I'd go with a GTX 460 just because you'll want a decent little GPU for some extra "oomph" when you decide to play that game. Not to mention that CUDA could help render if needed. I say this because there's no reason to have such a good CPU and a crap GPU in the same computer. One should be at least decent if the other is going to be up to date. =D
+1 on the GTX 460. If you want a good mid-upper level card that will get good longevity and allow you to play that occasional game, the EVGA GTX 460 SC 768 MB is a solid choice (SC for superclocked). It's already overclocked out of the box to run at 763 core and 1526 shader, and if you did want to play with the clock settings EVGA's precision software makes it fool-proof to tweak the card, but you don't have to; this card will play nearly anything at or just below high/full quality settings. The card has good connectivity with 2 DVI and one mini-HDMI out, plus it comes with it's own HDMI cable (nice savings there). Would make it real easy to hook up to that LCD TV you have.
Just saw it on Newegg for $179.99, and after rebate $154.99, can't go wrong with that price.
