Do you think it is worthwhile to buy an e7400 to overclock to replace my e2160 for gaming? I currently run my games on a 28" monitor with 1920x1200 native resolution. I have some FPS drops playing l4d maxed out and I was thinking my processor may be the bottleneck. I have a 4850 512mb and 4 gigs of ddr2 ram. Any input would be helpful.
