I had low 3DMArk05 scores.... at about 6500. Most forums suggest that this is due to the puny Intel 3.0ghz limitation.
SO I decided to overclock the hell out of it in hopes of saving my rig. Since I am a noob to overclocking... i had many start and stops... finally managed to get a stable clock at 3.45Ghz.... And the results were very encouraging..
New 3DMark05 score at 7498!!!
Does not touch the 8k++ figures some others are putting up.... but my 7800GTX is not OCed yet... still stock at 430/1200. At least now I feel better about my rig. Game play is slightly better as frame rates have improved.
Next will have to learn up a little bit more about OCing to higher frequencies... next target 3.6Ghz!!
