lol most games don't fully utilize 2 cores let alone 4,I would just save my beans and get an i7.
E8400 - E8500 is your best bet if your on a cash restricted diet,GA-EP45-UD3P is nice cheap board and ram they practically give away.
Can easily OC the E8400 to 4ghz on that board.
Also beat them to 6.5ghz
