Your cpu is too slow to use anything faster than a 6670.
It would be a major improvement over what you have now, and you wouldn't need a new psu.
Yes I'm saying don't waste any more money on that computer.
It would be a major improvement over what you have now though.
Friend, I will take your advice. I'm done with retail throw away computers. I'm gonna try my hand at a build next. Newegg also has the Sapphire version HD6670 Low Profile for the same price. From what I've read, Sapphire seems to be the top version for AMD cards. Do you have an opinion either way?
