well im thinking of upgrading my cpu to a 5400 2.8 cause just got a ati 4850 and my 3800x2 is a bit slow for it.thing is my mb only supports one of the 5400s and not the other which has avs next to stepping what does this avs mean?they are both same stepping and core g2.im not overclocking my 3800x2 cause im selling my mate this and it will only cost me 30.00 so not really worth the hassle.
