I bought a Dell Dimension earlier this year, and it came with an ATI Radeon 9700 card, not an Nvidia. Frankly, I'd avoid Nvidia cards like the plague. They're cool when they work, but IME, they have a very high rate of failure, at least right now. We have them at my office, and they're constantly going bad. Several friends of mine have also had their Nvidia cards go bad. I've been pretty happy with my Dell. The biggest problem I've found is that the USB ports are a bit underpowered. My machine came with 8 USB 2.0 ports, but there's really not enough juice to use them all. (Of course, I have a lot of stuff connected to my USB ports: external hard drives, Zip drive, scanner, video capture device, graphics tablet, printers, etc.) A powered USB hub solved that problem, but it took me awhile to realize that was why some of my devices weren't being detected. (It's a known issue with Dells.)
