[Solved] Need custom build advice

I need to build a cheap PC for my uncle and he wants it to be fast so I was thinking dual core cpu, maybe a 2.2Ghz. He wants at least 2GBs of RAM. He wants it to be under $300 with out monitor, keyboard, mouse. Any suggestions for what I should get?

You didn't mention an OS. If you need one, that budget isn't going to work.

Also, stay away from the older AMD CPUs like that brisbane. They are garbage. If you're looking for a cheaper CPU, look at the e5200. Throw a cooler on it and it'll OC like a champ.

overclock for his uncle? isn't that a overkill? why would he need that?
taking dump the Brisbane amd cpu and get this Athlon II cpu http://www.newegg.com/Product/Prod [...] 6819103688 if you are in the us and fancy email rebates, you can get this ECS 780M chipset mb http://www.newegg.com/Product/Prod [...] 6813135235 which after mail rebates will add total of 10$ more. if you don't fancy mail rebates, you can take this foxconn mb http://www.newegg.com/Product/Prod [...] 6813186166 with chipset of 760G.
both of them are future proof (e.g. you can replace the cpu with a phenom II x4 without buying new mb), the first mb's pro is that it can play FHD without a problem and it has a ATI Radeon HD 3200 gpu o/b.
the second mb's pro is that cheaper but can't play FHD well and has a ATI Radeon 3000 gpu o/b

The OC is to get more speed for free. The OP said his uncle wants it to be fast, but in this price range, no CPUs are fast.

BTW, those boards would bottleneck a phenom II x4. It'd be a waste.

There's nothing to maintain with an OC'd CPU. PC's become slow because users don't know how to keep their systems clean.
