Considering you have an Intel branded board, I'd invest in a platform upgrade instead of a GPU upgrade at this point.
I had a Q6600 running at 3.4 ghz for a long time... backed off to 3.0 in the last few months I used it... but switching from that cpu in a 780i motherboard to my 3770k in a z77... with the same gpu, I tripled my framerate.
It might be ok for single player games, but anything cpu intensive just will not handle it. From 20 to 90 fps in D3, 20 to 65-70 in GW2, RIFT? 15 to 45 fps...
Using a GTX 465 and maximum settings (including AA) on a 1920x1080 monitor. The cpu upgrade alone was so huge it was absurd. I love my q6600, but games need something better now. Single player stuff was ok, mind you. But that is about it.
Being at 3.6ghz, it might make an improvement... but I can't see that it would be worth getting a 670 and nothing else. Maybe pick up a 3570 or something, and throw it into a midrange motherboard.
