Okay guys heres what's up...... I recently upgraded from a Q9550 to an i5. I also am a proud owner of a 5870. With my old Q9550@ 3.6 I would run Futuremark and score in the P17000's to P18000's depending on the GPU overclock. So I now run Futuremark with my i5 @3.4 and now get an overall score of mid P15000's and that's with the 5870 overclocked. My CPU score with that CPU overclock is around High 14000's so I don't think it's any problems with my CPU. But for the life of me I can't figure it out. So I will list my old set up and new setup also drivers and Windows Versions. If anyone can give me an Idea it would be a great help! Old System: Q9550@3.6 Gigabyte EP45-UD3R G.Skill DDR2 80MHZ 2xWestern Digital 500GIG HDD 7200RPM Raid 0 Diamond ATI HD5870 9.12CCC Drivers Corsair 750TX PSU CM Hyper 212 Plus HSF CM Sniper case Windows 7 64bit Home Preimum New System: firstname.lastname@example.org EVGA P55 LE G.Skill Ripsaw 1600MHZ@1600MHZ 2xWestern Digital 500GIG HDD 7200RPM Raid 0 Diamond ATI HD5870 9.12CCC Drivers Corsair 750TX PSU CM Hyper 212 Plus HSF CM Sniper case Windows 7 64bit Ultimate (Not so on the up and up?) Now the only other thing I can think of is..... my new copy of Windows 7 Ultimate. The copy I have was given to me by a friend. I found out it wasn't so much on the up and up. So I have a new OEM copy of Home Premium on the way from New Egg. I also thought it might be the Video card drivers but I was running 9.12CCC on the last system as well. So I don't know any thoughts? Right now I can't use it to much more than off line because of that crappy copy of windows. So there is know rush but if anyone has an Idea I would appreciate it!
