Hi pca,
What bugs me with my GeForce's TV out is that it only allows me to adjust the image position on the TV out (up, down, etc) with no option to adjust the sizing. The output image doesn't display full screen.. it's annoyingly smaller. Is this not a problem with your ATI?
A dual headed setup would be nice... reading PC fonts on a TV screen has often proved to be guess work for me

. Some of Matrox's cards have the feature - can anyone comment on these cards?
I also plan to run Win2k, but after some thought I realised FAT32 filesystems in Win2k can't exceed 32 gig. Instead of using NTFS I think I'll rather use my current BSD box for the storage and just Samba mount to the win2k machine via (hopefully) wireless.
Another advantage of taking this route is that the win2k machine can be assembled with a smaller case, perhaps even a slimline desktop (horizontal) case.
Thanks,
Aragon
