this is getting funny now,i know nothing much in the way of hardware,but would i reccommend a fx4100,nope,its the same as trying to sell someone on a i3 chip.
the athlon x3 is a broken bit of junk really,its got a locked core,because its junk.
what i would recommend is the fx-6100 and a asus m5a99x,because there ment for each other.
another cheaper choice is to get an fm1 mobo for £60-80 and throw in a athlon II x4 for £60 = £130.
but the new apu are coming and waiting for fm2 mobo with a A10 5800 would be better still and under £200 for both cpu and mobo.
fm1 and athlon? will that work?
