Hi Everyone! I have decided to buy a PC over a Mac due to money constraints. Anyhow, I found a used PC on craigslist, and it features the following; HAF 922 case 3 120mm fans, 1 220, 1 140 EVGA x56 3sli mobo intel i7 930 processor xfi 5850 radeon videocard 6 gig ocz ram 1600mhz xfi fataily sound card samsung cd rom megahelm cpu cooler 500 gig 32mb western digital black harddrive cyborg keyboard mx500 mouse senhieser 280 pro headphones very slim lg 23" monitor W2340VG If you were going to make this purchase, what would you do to ensure that this machine is well worth the money ($800). How do I check what type of CPU and graphics card it contains? I have little familiarity with windows. I haven't had a computer for the last three and a half years, and have don't all my Internet browsing through my iPhone. Therefore any advice would be welcome! Thanks for your help. Oh, and the reason I have this posted here and not a PC site is because I like this community, and visit macrumors forums more than any other. I hope it's ok to ask this here. If not, mods, please delete this thread.
