I have an AMD AM2 x2 4600 on a nforce4 chipset with 2g ddr2 value ram with an nvidia 8800 gts video card. I was thinking of upgrading to an Intel core 2 duo e6750 on a p35 chipset with 2g Crucial ballistix ram. I think the upgrade is a better match for my video card. But I was wondering, will I see that much improvement in performance? And would the cost be justified?
