Now that I've bought my new AMD64 system, I'm very keen to try the BETA Windows x64 versions. While doing a bit of reading up around the subject I noticed, to my surprise, that the Intel PIV Prescott and Xeon's support the x64 extenstions too! I have just finished burning the build 1247 of Windows Server 2003 for x64 to CD and am installing on a nice new Dell 2850 with 2X3.4GHz Xeons. It should be interesting to see how it compares. I'm gonna pop in 8GB of RAM just to see if it really does support...
