Well thanks maurelie,
If thats the case then I think also start considering ATX mobos. Which ATX do you think is sufficeitn enough to get max from fx-6300 and also uses the new chipset ?
There aren't any good mATX motherboard for the newer Vishera/Piledriver CPUs like the FX 4300, FX6300 and FX8300 series. They are labeled as AM3+ motherboards but they use old 760G chipset which is not very good for AMD X3XX series.
There is much better mATX support for Intel CPUs
It depends on your budget. 970chipset can be found at $60-$100, while the 990chipset starts form $110 and up
If you want mild overclocking, get the Asus M5A97 R2.0 or Gigabyte GA-970A-UD3P both of them $90
If you want better overclocking and SLI/Crossfire support, get Asus M5A99FX PRO R2.0 or Gigabyte GA-990FXA-UD3 both around $120
And the ultimate in 990chipset is Asus Sabertooth 990FX R2.0 at $180
