My PC has never really seem to run at its full potential, i may be wrong but i just want to make sure. Im questioning my Winxp64, does a 64bit OS that isnt using 4 or more gigs of ram tend to slow down a PC compared to a 32bit system? Im comparing my system to my friends PC which we built last Christmas. here is his setup: e6750 OCed to 3.4 with aftermarket HS/F 2 gigs crucial balistix PC8000 Powercolor HD3870 Asus P5E X38 WD caviar SE 250 gig sata 700 watt psu My system is listed in my specs. My start up time seems longer than his, pausing in and out of games to the desktop is defiantly slower, he would have instant response from COD4 but when i do it from COD4 it takes about 5 seconds and waits on a black screen then goes to my desktop. his 3dmark 06 score was 12300, mine was 13000 with the 8.8 beta drivers but it has dropped 2000 points by switching to the 8.8 final release drivers. But my computer seemed to be slower than his even before i made the change in drivers and had the 13000 3dmark06 score.
