My parents needed a new computer down stairs for guest, because one time my mom was naked in her room, with her computer room accross from her room, and a guess came up to use the computer and almost saw her, but almost was enough for her to get a computer down stairs
I dont plan on overclocking at all. I plan on gaming(Just MMOs like WoW nothing too graphic demanding),and for people to surf the web.
Preferences: Intel, Corsair PSUs(ive found them more reliable then any other psus)
The accessories(mouse,monitor, etc) have already been ordered so technically my budget is $500 for the computer parts.
I would seriously consider going with AMD with your budget so that you can get a DDR3 mobo and at least an X3 CPU.
The game you have mentioned is VERY CPU dependant, in fact it is one situation that a decent CPU may be even more important than your Graphics Card. You don't want a dual core CPU for gaming these days, another reason to go AMD instead of Intel as Intel Quad is very expensive.
Your HDD is ok, but the Samsung Spinpoint F3 500gb is same prce and is faster so I would swap them
