thanks guys. I've done some reading and my venerable 875PBZ board only has AGP and there is no really viable (for me due to the number of PCI slots I need) upgrade path. Albatron do do a socket 478 PCI-E board but its tiny and doesn't do what I need so i'd have to replace, board, cpu, RAM just to get a PCI-E board. oh an reinstall my system as well.

I was leaning to the Gainward 7800GS+ but that's an expensive card, especially when it seems the yet to be released X1950Pro from ATI will beat and do it cheaper.

so fingerts crossed.
