eh all i kno is my nice 32-bit processors runnin win2k3 server (32-bit edition) real nice an i eh have no complaints. i sure as hell kno i eh going 64bit until dey have "corporate editions" of windowsXP 64bit an win2k3 server in distribution. an also i eh going dat way till intel bring out a PROPER 64-bit processor. dem itaniums look to me like dey is crap... an expensive too... an real slow too... so wen intel come out wit dey p5 wit 64bit processing capability or a celeron wit 64-bit processing capability, i mite invest in it, jess to fool around wit de technology.
