Should work. You may want to get an 8600gt as the price is about the same, but 8600gt is a lot faster. You should get at least a 500w system, atx. Just make sure it's compatible with your motherboard either 20+4 pins or 24-pins, w/e your motherboard requires and has cables for sata, pci-e, etc...
first let me say if this is in the wrong place sorry
