Those are replacement parts already in it. I want to upgrade the resulting Frankensteined computer. I have up to 600 dollars to work with,

In that case, get

as a videocard for $499 and

as an SSD for 69.99 (Much worth it)

Do you already have a case, fans, etc.? If not, downgrade the graphics to a 280x (~$299) and get a decent case and air cooler.

Also, do you already have Windows 8?
