OK, i'm clueless when it comes to picking out computer hardware, but love to play games on the computer. What kind of Graphics card could I put in an HP dc5700 Microtower that would be good to play games with? I inherited the computer from a friend and would like some better graphics so I could use it to play games with.
It looks like this is your system which means no PCI-Ex16 slot. Probably your best bet would be to go with a straight PCI card. NVidia's partners are still pushing out PCI cards (though not AGP), so I'd probably go with something like this Geforce 9400GT PCI.
The only PCI-Ex1 graphics card listed on Newegg.com is the ATI X1550, which is why I recommended going straight for the much newer 9400GT PCI card. You'll never get uber performance out of any card you put in there, but it's a far cry better than the on-board chipset.
Actually, if i'm looking at everything right, the computer has 2 full-height PCI, 1 full-height PCI Express x1 and 1 SDVO/ ADD2 connector. but the 9400GT is a PCI Express x2. does that make a difference?
