Screen rotation update

The latest on my screen rotation problem is that it appears to be a known bug with Windows XP service pack 3 and quite a few graphics cards, and probably isn't readily soluble. It appears not to affect motherboard graphics, but I need the performance and don't want to give up the memory motherboard graphics need, so for now I'll pass on that one. Not the end of the world but VERY annoying.

I'd go over to Linux, but there are just too many Windows programs I use that don't have good alternatives. Or Windows 7 might fix it, but I really don't want to have to reinstall everything.

Boggle...

Is there any way a refurbished NVIDIA GeForce4 MX 32MB 4x AGP Graphics Card for a Mac (presumably an old mac with AGP slots) can possibly be worth 50 quid?

Do the mac ones differ from everyone else's AGP graphics cards in some way? Because they look identical!
