I use a Lenovo (IBM) Thinkpad T43 with the ATI X300. I use Linux
(Debian) only on this laptop and with the fglrx ATI driver it certainly
gives acceptable performance. I can spin a 300-residue protein drawn in
surface mode easily enough. It seems to be only a little slower than my
desktop, which has a ATI 9500 Pro.
I don't recall trying it on this laptop before I blew Windows off the
disk, but I'd expect you'd get at least as good performance with Windows
The Thinkpads are nice small laptops.
