I have games that require Geforce 7900 GTX or X ATI Radeon 1900 XT 256 MB or better however I only have PCI and AGP slots. Id there a graphics card that will do the same for PCI or AGP and could some one tell me what cards I could use in it's place> I have an HP d325 with AMD Athlon 2800+ with Barton, 2 gigs Ram, socket 453 organic PGA, 1.95" x 1.95". also can I speed this unit up some how.
If you don't want to upgrade your cpu/motherboard, your expenditure would be less performance efficient because agp cards are costlier and single core cpu would bottleneck the graphics card's performance.
but you have to make sure that your PSU can run it properly. If you don't have a unit of over 400W with at least 18A on the 12v rail (though you may squeak by with dual 14A 12v rails) then you are going to probably need to upgrade your PSU. If you don't you risk damaging your system. Anyway if a game requires a minimum of a Geforce 7900 GTX or X ATI Radeon 1900 XT I can't imagine that your CPU would meet the requirements.
