This is from the Tom's Hardware article right? Yeah, his specs are WRONG for the 5900XT. Most were 390 and some were 400. It's funny because there is another article several months later that refers to the 5900XT being 300 MHz and how this card they're reviewing is so great because it's "overclocked" to 390MHz, but it's really just running at the same speed as every other 5900XT. Jounalism at it's finest.
390/700 is stock speed, though you can find ones clocked at 400/800 out of the box. My eVGA card would overclock quite well on the core (~450) but not well on the memory (~720). The XTs are rumored to have tighter memory timings that help make it almost as fast as the plain 5900. If you look at reviews, the 5900 and XT tend to be very close with the 5900 taking only a slight lead.
The thing about my 5900XT is that I don't use it. Shortly after buying it I got a Radeon 9700 that overclocks to well beyond 9700 Pro speeds, and it utterly trashes my 5900XT in the games I play (mostly Battlefield Vietnam and UT2004) Where the 5900XT would run smooth at 1024x768 no AA/AF I can now run 1024x768 4xAA/8xAF with the 9700 and get the SAME framerates as I would on the 5900XT without AA/AF. Or I could run 1280x960 and get HIGHER framerates with the 9700 than I was getting at a LOWER res with the 5900XT. It was a night and day difference, and my 5900XT has been relegated to my backup machine.
Do yourself a favor and unless you're getting this card for OpenGL use only, Get a 9800 Pro instead.
