Thats not very budget. I would say go for some better RAM, other than that it's lookin pretty sexy.
By budget, I thought you meant 4 or 500. I hate it when people say "I have $500 and I want you to build me a really nice computer that I can game with". For $500, you are not going to get a good computer that you can game with. Didnt mean that towards you, I was just saying in general. That was what I thought I was going to end up saying, but, alas, no need for it. I underestimated thee.
