I have always used Nvidia chipset VC. But the HP laptop my husband took to Iraq with him had an ATI in it and it was pretty much done once he came home. Of course the heat and sand could have been what killed the card lol.
Jealous of the liquid cooling systems Im seeing in some of yours.
Been wanting to try one out in one of mine but its just not realistic with us being Army and moving alot. Besides Army movers are the worst.
