Help my buy a PC?

[Zlejedi]

Buy this:

http://www.newegg.com/Product/Product.aspx?Item=N82E16883227136

and get geforce 9600gt or radeon 4670 graphic card (or radeon 4770 if it's still inside your budget).

I have no experience with us shops for obvious reasons but if you get both parts from one shop they should put it together for you ?
