hello to everyone!!sorry for my english(i'm greek). i really need your help guys. i do not have problem with my pc(thanks god) except from the big working temperatures (60 and 70 degrees in windows and gaming mode respectively) but i have a couple of questions to make. i run 3dmark03 when i was just build my pc (intel pentium D 830, asus P5WD2 premium, 2x512 corsair XMS2-5400UL extreme low latency, msi NX7800GTX 257mb and 74Gb WD raptor) and my mark was about 16500. that's ok with that. but then i realized that my memory was running at about 553mhz by default(i don't know why, ask asus). so i changed this option from bios and now my memory is running at 820 Mhz ,cpu is running at 3,1(not great difference i know) and i also bought a second raptor 74Gb and i set up a raid 0. i tried the 3dmark03 one more time and the mark was the SAME!!and now the question...does 3dmark mark the capabilities of just the graphics card or the capabilities of the pc as a unit???the other question is:when i compared my results with the results from onother pc's with same specs i saw that there was a great difference(at about 3000). have i done something wrong? sorry if i was boring.thanks anyway!!!!!
