HD2900xt w/e8400@4.0ghz. I think my gpu is bottlenecking my cpu am I right? I put the new cpu in and ran 3dmark06 and came up with maybe 300 more points than with my e6600@3.6ghz. My scores are in the high 12k's, nothing to really complain about but that's what I think is going on. Just wanted some input.
