Hi all, I recently got an older Athlon 64 X2 4200+ based system that I've installed XP on to make playing some of my older games easier. Currently I'm using the integrated graphics which work fine for most of my games, but I'm looking to throw an older Nvidia card into it to give it a little more horsepower. It has a first gen PCI Express slot and a 250 watt power supply, so I'd like to go to something that doesn't require any external power. The most demanding game I'm likely to play on this machine is Bioshock @ 1280x1024. Thanks in advance!
