Can somebody tell me if this cpu upgrade is worth the money? I have an E4600 dual core running at 2.4ghz (2M L2 Cache, 2.40 GHz, 800 MHz FSB). I was looking at upgrading to the E6700 2.66ghz (4M Cache, 2.66 GHz, 1066 MHz FSB). Is the extra cache and small ghz increase worth it for $50.00. Does the different front side bus speed matter? thanks, I was wanting a bit more performance in games with my new video card, a gtx 460, until I buy a whole new pc. Would this show me any improvement in gaming or should I just wait until I build a new pc. Thx
