I was looking around for a friends old HP computer that has no AGP slot, and is using onboard graphics. He cant play much on that system and was looking to pop a decent card in there for some light gaming. I see NVIDIA MX4400 and FX5200s are made in PCI, along with ATIs 7200. Any thoughts on what might be the better card? All of these can be had for less than $20 on eBay (which is what hes looking to spend). Thanks!
