MasterScottyy, sorry if all these numbers look like technobabble, but building your own computer is actually not all that hard, most of the hard work is in the parts research, but then, thats what this forum is very good for; suggesting components to buy to give you the best performance for your cash.
Do you need a monitor by the way? and what kind of performance are you looking for? The component list suggested would play just about any new game very well.
Translation:
