As the title says, I just built a new system and the performance is actually worse than the machine it replaced. Old Machine: P4 2.6C Abit IC7-G 9800pro 128MB 1GB Corsair XMS PC3200 (256X4) WD 74 Gig Raptor New Machine: A64 3000+ Venice Asus A8N SLI Deluxe 6800 GT 256MB 1GB Corasair XMS PC3200 (256X4 from old machine ^) WD 74 Gig Raptor (from old machine ^) Now the game I am playing is World of Warcraft. On my old machine it would take about 5-10 seconds from when I entered the game to when i could actually start walking around. This was due to the game loading information into RAM. (upgrading to a gig from 512 confirmed this.) With the new A64 system this lag time has at least doubled. Furthermore, I get random lag in highly populated areas where the game will stall for 3-5 seconds. This never used to happen with my P4 system. Now I know that the A64 and 6800GT are far more powerful than my old rig so what is the deal? No other software is installed and I have the latest chipset and video drivers. I've tried reformatting twice now and the lag has not changed. Any ideas?
