Hey guys, so recently my mom gave me her old work desktop. It doesn't work, and I'm pretty sure its the hard drive. Anyways, i really want to play some games that i can't currently because i have a mac. I want to play space engineers and maybe start citizen when it comes out. The dell vostro 200 has a lga775 socket and I think it supports ddr2 ram. Im most likely to upgrade the cpu, gpu, and ram. Any ideas on how to do this? Please help! I need answers ASAP.
