MY current build is an am2 4200 dual core @ 2.2 ghz and does not overclock, had problems with it getting to 100C, system failure, etc. My motherboard is an m2n4 sli, 2gb ddr2 @800 mhz, 9800 GTX. My cpu bottlenecks my gpu, my proof is because no matter what settings i have The Elder Scrolls IV Oblivion at I get no better performance, hdr can be on, off, AA off or on, it's all the same performance. I was wondering how well would a q6600 and a new motherboard + PSU would run on a 9800 GTX? I want the quad because it is more future proof and would not have to upgrade nearly as soon. I have the money to make the upgrade, should I do it, take my old parts and rebuild it into a new pc and sell it off to make up for what I've spent? Views and replies greatly appreciated.
