well, I took my stock power supply out and put a new one in so I could install my x1900 , and my 4700 had four
ram slots.... hrm....
they have a very small upgrade option, but now if I want to upgrade, it looks like a new case, motherboard, and processor for me. I just recycle the rest of my parts into the new one.
I think its always been
Nvidia - intel
ATI - AMD
I heard that some future cards were going to have PPU's on them, but I think heating issues came into play...
dissapointed about hearing about ageia physx.... I keep reading that its a pretty awesome bonus to have in a system... I guess only for 3d mark though.
