Really? Wow i didn't think that processor could keep up. All I hear about is how awesome quad core is for gaming and all that, so I just assumed I needed a new one as well. Ill look into OC'ing it in the near future.
I usually play my games at 1440x900, which looks great. And my rig in its current state hasn't let me down once, ever. Play games like Warcraft, Call of Duty, Total War mostly at high settings.
Thanks for the replies!
For your resolution,you'll definitely see a performance boost with a faster CPU because low resolutions benefit more from a faster CPU compared to higher resolutions(which are more GPU limited).
Also games like Total war series benefit from a quad core CPU.
So overall,your CPU is fine but upgrading to a quad core will give you a good boost in performance.
