Will my e5300 bottleneck my gtx 460? I have 2 gig ram I'm also thinking about upgrading it to 8 gig ram. Do you recommend 2 sticks of 4 gig or a single stick of 8 gig. Is it okay to finish with that build? Any suggestions?
Any bottleneck will be minimal, and then only in certain games.
Always better to use a pair of MATCHED sticks of memory in a dual channel system. Faster (with 2) and less chance of memory errors (with a matched pair).
