it has built in INTEL graphics, and i want to know what graphics card i can buy to put into the pci/pci express slot. can you give me a link to the best one possible.|||You can put in any PCIE 16x card you want into the system.



There are only 2 limits -- the size of your chassis (which determines whether or not you are able to use large video cards in your computer case) and the power supply unit (powerful video cards require a high wattage power supply).



But seriously though, that Pentium 4 processor is pretty much going to bottleneck any new video card you put in it. At most you might be able to use a Radeon 5670 or GT 430 -- any card more powerful than those is likely going to be held back by the slow performance of the CPU.
