Upgrading to Windows 8.1 Pro on a Dell Dimension 8250. Can't be done unless you change processors. But I don't know which on of the Athlon 64 x2 processors will fit or work. It's a shame Microsoft wasn't more specific with their hardware requirements for Windows 8.1 Pro, had they been I'd not be out $200 for the upgrade I can't use. Can't seem to find squat on Dell about this so here I am asking at tomshardware. Help please!

The original CPU is made by Intel and there's just no way to replace it with an AMD one without changing the motherboard.

This motherboard is used and priced at about $50 with free shipping not sure if it's worth the hassle suggestions please!
 
AMD made two versions of the 4400+. Be sure you have the correct one. The 4400+ x2 toledo core was a socket 939 and won't work on that board. The newer version of the 4400+ is a socket 940 (AM2). You need to cross refernce the part# on the CPU with AMD's processor list.
