I want a Phenom II x4. . .(say i dont know (now i do) but say i dont know that socket thing)
Im looking at motherboard's "compatibility" - Phenom II x2 / Athlon II <-- not ocmpatible with II x4?
or another example Phenom x4 / Athlon x4 <----- not compatible with Phenom II x4?[/color]
Thing is Phenom II and Phenom are the same thing? (same for athlon)
if the socket is the same (say am2) a motherboard will read Phenom II x4 / Phenom II x2 / Phenom II / Phenom x4 / Phenom x2 ? (if they are all am2)
The first Phenom sucked ass. It couldn't clock worth shit, and the performance was barely better than an Athlon 64. Phenom II and Athlon II chips have been known to overclock really, really well and their performance is reasonably close to that of a similarly clocked Core 2.
All AM3 CPUs, Phenom II X2, X3, and X4, Athlon II X2, X3, and X4, will work on all AM3 and all AM2/2+ motherboards. AM3 means DDR3, which AM2 and AM2+ chips(All Phenoms, some Athlon II and Phenom II) do not support. AM3 chips can use either DDR2 or DDR3, depending upon the motherboard used.
At this point, there's no reason to get an AM2 or 2+ board unless you need to save $50 - $70 on the board and memory, or if you already have an AM2 or 2+ board and want to upgrade processors. Just get an AM3 board and AM3 processor. You'll still spend less than you would on a dual core i3 chip and matching board.
