agree'd with stickmansam, get a good 970 or 990fx am3+ board and go steamroller. It'd be the best upgrade, the athlon should hold u over a little longer. But if u really had to upgrades would be a phenom ii x4 thats 95watt, or a phenom ii x6 95watt like tigerdirect still sells a 1045t new for around $120, but its a 2.7ghz clock speed, and will hold u back. My stock 1055t holds back my 5850, and an oc to around 3.4-3.6 helps performance. 2.8 to 3.4 made ultra bf3 smooth with no lag so the lower clock speed will hurt.
Finding a over 3ghz x4 will be difficult on 95watt board, and the x6 is prob only a small upgrade. So reasoning for steamroller and a decent am3+ board is best way to go
Thank both of you for your reply. Very much appreciated.
I have never heard of steamroller, and can't find a review on it so I'm guessing its yet to be released? Ill upgrade fully mobo and cpu, but is the steamroller comparible to i5 or should I just go all out with the i5? Might as well make sure this comp will be able to last a couple of years before another major upgrade.
