Wow... is the GF4 4600 that much better than the GF3 Ti 200?
I have an MSI KT3 Ultra2, AMD Athlon XP 2000+, 256MB PC2100, and a Gainward GF3 Ti200 at 230/500Mhz, and my score is at around 7500.
Is the pickup you got from the GF4 LePaul? Or does that extra 256MB of RAM make a big difference? I guess you've also got 128MB of VRAM on there too, and I'm only pushing 64... (only? I remember when a 4MB card was awe inspiring!)
