Okay, I'm looking for some help in either buying a pre-built computer or making my own that can run the following games in as best quality as i can: Skyrim, The Sims 3, Bioshock Infinite, the new Devil may Cry, The Witcher 2, Diablo 3, Tomb Raider, Guild Wars 2, Left for Dead 2, League of Legends, and maybe Crisis 3. I won't do much else on this computer except for gaming and internet browsing. I'm a college student so I would like to not break the bank on this, but if I can get a computer that can last me a good decade or two and be upgraded to handle most of the games that will be released for a while that would be worth a little bit extra of extra cash. I've not built my own computer myself but my father has some pretty extensive knowledge and can help me with putting one together so I wouldn't mind doing so. Any help with this would be amazing! Thanks in advance!
