I like my new
8800 GTS with support for DX10
As a point of reference, with the GTS I was able to turn every game option setting to max and zone into my house with something like 20 pets and 300 items and had virtually no lag.
I do notice the ocational dropped frame when moving around ALOT, but that's probably due to several factors off the vid card. Haven't noticed any lag when camping one area. One nice thing about this card is that I wont HAVE to upgrade it any time soon. Its DX10 and SLI ready, so if I need more power later I can drop in a second card for a total of 1.3gb and a processing bump. When DX10 games come out, I'll actually see the improvements
