I have an Sapphire 9800 Pro, and I'm not having these problems. My Guess is, that this probably isn't the cards fault. I also got the cat 4.8.
On a side note, when I had installed SP2, BF42 crashed right upon clicking the desktop-icon - rebooted my PC. Deinstalled SP2 - Working again. What a ServicePack is that supposed to be?
My System
ASUS A7N8X (PCB Rev2) Bios 1010 - latest nforce Drivers
AMD Athlon XP 2400+
512 MB Infineon RAM CL2.5 PC333
Sapphire 9800 Pro 128MB + Cat4.8 w/o SmartGART
Creative Labs Soundblaster 5.1 Digital
Windows XP SP1
