Not really looking to overclock, but i already got the motherboard and now i'm trying to get a CPU. I have a Gigabyte nforce590 board and want to get the fx-62 CPU and it says on their site in the CPU suport list that this CPU must have a F2 stepping, does this mean no other FX-62 will work with this board? And how do i find out which stepping the CPU is before i buy?
