Just recently got a Radeon 5770, great card for the money! Performance has been very nice, but I was just wondering if my Core 2 Duo 6700 @2.6 GHz is bottlenecking my performance. Not that I'm noticing any problems, its just that the cpu is almost 4 years old and was wondering if i was to get a new motherboard with a core i5 or i7 if my gpu would expierience a performance boost. Thanks!
