|Desktops for the new Windows XP Pro x64|
Microsoft has finally raised the curtain on its 64-bit version of Windows. You can take immediate advantage of the new OS if you have a PC with either an AMD Athlon 64 processor or an Intel Pentium 4 600 series chip. AMD's Athlon 64 line, introduced in 2003, spans all classes of PC, from budget systems such as the eMachines T6212 to gaming rigs such as Alienware's ultra-high-end Aurora ALX SLI. This past February, Intel released its first 64-bit desktop chips with the Pentium 4 600 series. Like the Athlon 64, Pentium 4 600 chips run 32-bit software with the ability to make the leap to the world of 64-bit computing. In addition to more powerful software, the advantage of a 64-bit platform is that you can exceed the current 4GB memory maximum of 32-bit PCs. If you are clamoring for 64-bit Windows, here are five PCs that'll run Microsoft's new OS.
