Ok first of all, here were my previous PC specs: CPU: AMD Athlon 3200 XP Videocard: ATI Radeon 9800 PRO 256mb Motherboard: ASUS A7N8X Deluxe Power supply: 400W All I can name for now, but here's the thing. My Radeon 9800 broke down on me so I replaced it with a Club 3D GeForce 6600GT 128mb, which in theory was supposed to be on the same level, if not higher, than the Radeon 9800. But to my shock, the performance has been significantly reduced. This is immediatly apparent to me when I started WoW: Wrath of the Lich King. It was already at the title screen, when I noticed the frame rate was a lot slower than the very smooth one I had with my Radeon. Any ideas?
