I have been a lover of XP since it came out. I did try and loved W2K3EEx86 as well, but its got some unfriendly things about it when used as a workstation. Which brings me back to XP. Been thinking of the x64 bit version. I am told that its the best of W2K3 but designed for desktop use. I need to hear from people who use it as their main rig, daily use. Can me and all my free tools that work on XP, move over to XPx64? What will I FEEL when seated at this rig, when compared to regular XP. Intel P45 mobo, C2D-Q9300 (Quad-core@2500mhz) 6GB ram, 60gb SSD, nVidia GTS250, Intel GB Nic, realcrap sound. Tell me the Pro's and Con's.
