Glad to hear someone still likes AMD. I tend to regard AMD as the Linux
of hardware - y'know, the underdog. Pity they didn't keep the lead they
had when Intel was telling everyone that 64bit would never come to the

Yeah - although to be fair (and I have no intention of doing that), the
sort of people who read those sorts of articles are gamers rather than
professionals, so framerates and so on are of interest, rather than
ability to get real work done.
