Mine's an ancient Creative TNT2Ultra 32MB. It may be old, but it suits the BP6 perfectly. No mods required, AGP 2x, and it has a TV out for watching my DVDs.
I've had that card since before I got my BP6. To think I spent £200 on it when it came out...
Agreed, InactiveX. I forgot my second BP6 has my old Diamond Viper 770 Ultra TNT2. It has worked fine since I got my first BP6 in August of 1999. Mine is 32MB and no TV-Out.
