nVidia for me because I've had some bad experiences with ATI cards.. I might be willing to try again some day, but currently I'm quite pleased with my Geforce 4.
I've worked with ATI and NVIDIA cards in the past, but my GeForce3 has been rock stable since day 1 - as well as my Radeon 8500, but the nod goes to NVIDIA for this one, as only the drivers of ATI will someday extract the full potential (aka performance/features) out of the card(s).
Wish I knew something about PC hardware so I could join in thse disgussions.
Yeah, I like that GeForce card, (just smile and nod Justo, smile and nod).
