My ram is ddr2 I just copied that junk from a website that had my computers statistics. I am not sure about the motherboard though I havent done anything to it yet but I'm gonna open it up later and see what kind of surprises I'm in for. Btw its an HP pavilion a1523w.

Im not much of a computer buff so how much work do I need to do to my pc to make it run gta4 at at least medium standards? 1GB/2GB(max) ram Intel pentium D 820 dual core/ 2.8ghz L2 cache 2mb 16x dvd drive integrated ATI Radeon Xpress 200 OS:Windows xp Media center edition 250GB hard drive Aside from the GTA standpoint anyone have other suggestions to help it out? Money not being a factor, because I thought about upgrading the os.
