Dell at times uses eVGA cards.  But most of the good ones play about the same.

8600 GT version is a fair card only, but the GTS would be better and that also depends on the game.  Which games are you thinking of  ?

my 8600GT works great on games like Company of Heroes, UT2K4, Unreal Tournament 3 Demo etc... On higher settings too.

I have this card on two systems and it does great. The DDR3 is the big boost. Stay away from DDR2 versions of this card. Regarding the 8600GTS, it's not a lot faster than the 8600GT, so you really don't gain that much. I play mostly Battlefield 2, but I've played Supreme Commander with this card as well and it does a great job. I can turn pretty much everything on without a hitch.

i have that 8600gt card and it's pretty good actually! runs silent and very smooth on all the games i've played on it! there's really no need to worry about an upgrade at least till prices on better cards come down..... way down! i don't worry too much about overclocking either, cuz the gain isn't worth the risk!!
