ive been running my 8800 gtx, with a 320 gb WD Hd, Asus P5b Mobo, intel e6400 2.13 ghz, and 2 gb of OCZ PC 6400 800mhz ram ... the 3dmark 06 score i was getting with this was 8919 .... i bought another gig of exactly the same OCZ ram and since then ive been getting about 8600 3d marks, also in my windows experience index, the RAM sub score has gone down from 5.1 to 5.0 ...... i dont get why... the only other changes to my system have been to the case and PSU.... and my cpu does run a few degrees higher than it did earlier.... so what could be the reason ??
