I'm pretty sure I'm NOT going to crossfire. I picked the "Asrock" as first option for it's good price and it has a 1600 ram support without the need of overclocking my Mobo. Has what I want: SATA 6G and USB 3.0.
Second option. A difference in the price but no problem I can afford it if it's worth it and it was the best I could get as an alternative. There is also same model but with EVO. 5 $ more.
However the ARock Chipset is 770 AMD and the ASUS is AMD 870.
I guess getting my self an AM3+ board like "abekl" mentioned is what I should do. But I'll buy the phenom X4 955 and use for now it until the bulldozer comes in the market.
I will wait until the price of the bulldozer goes down from ~200$ to ~100$. Just like what happend to the phenom cores. Buying now will just be a waste of money, as I believe the (X4 955 BE) is powerful enough and can smoothly run anything for now.
Beside, I'm saving cash right now to buy myself a decent Asus 20" LCD/LED screen. ^^
Anyways you guys were right. An AM3+ board is better for my rig. No difference in price compared those non-AM3+. And who knows my cpu might run dead anytime and replacing it will definitaly be easier.
So.. It is a win-win case for me picking the mobo.
