I am a mad Nvidea card user
I lovethe things.
GForce cards are really good.
I think they got one now with 1 gig onboard. INSANE!
I also never been a fan of the Radeon Cards they tend to freak out on Intel's. I have tried a few times and after a while the Radeon just kinda malfunctions or fails with an INTEL. But maybe its just me. After 2 failures with radeons I am not willing to give em a shot.
ASUS and ABIT mother boards I highly reccomend also.
ASUS for Intel
ABIT for AMD.
