For 1024x768 then HD5670 is more than enough for you. Can you OC your CPU a little bit? If you can then go overclock it, you will see performance increase if you OC your cpu...
well i cant OC bcuz my mobo wont allow me .are u saying that i wont get any performance increase if i dont OC my CPU?
well thanks to all for ur quick and to the point replies.i guess i will go with the hd 5670 or i might even consider a gt 240.
actually the 2.0 versions don't have huge probs with 2.1 since most PCI 16x are backwards compatible, like how 2.0 was backwards compatible with 1.0. So you will have maybe, smalllll chance, that you'll face problems. I'd recommend the 5670. the GT 240 came out to be somewhat of a disapointment. Plus at the same cost, the 5670 is the better choice.
