trying to find out if this grapghics card is compatible or not the graphics card is : Force3D AMD ATI radeon HD 6450 2Gb DDR3 HDMI DVI VGA video graphics card PCI express pcie x16 HD 1080P windows 7/vista/XP
and the processor is an intel pentium 4 3.2ghz processor
It will be fine. Processors and graphics cards don't have to be compatible. Of course if you have a very fast graphics card and very slow processor, or vice versa, games won't run well, but that is not your case.
