from this: http://en.wikipedia.org/wiki/AMD_Athlon_64_X2 ?
I'm ordering from Newegg most likely, since it seems they have the lowest price by a mile, but they only have a replacement policy on CPUs, which means no refunds if it doesn't work out. I know that AMD2+ processors can supposedly fit in AMD2 socket, and I'm not dumb enough to try this on my own so I'll probably be sending it in to my local non-Best Buy computer store. However, is the motherboard itself going to stop the installation from working? (I know you would need the model to know, so if this is the case I'll find it.) And even if the putting-in-place part works, what exactly will I have to do to update the BIOS? I just don't want to go in to this half-assed and screw up my computer. Thanks.
Well, apparently when I was comparing the socket types I was misreading Phenom as Phenom ii, and therefore AMD2+ as AMD3. I won't be needing your help right now, but thanks.
