kir4n :
Hey can u please give me the link to get some information about these two motherboards...
kir4n,
The M4A89GTDPRO PRO/USB3 is at http://www.newegg.com/Product/Product.aspx?Item=N82E16813131631&cm_re=M4A89GTD_PRO/USB3-_-13-131-631-_-Product.
The M4A89GTDPRO PRO is at http://www.newegg.com/Product/Product.aspx?Item=N82E16813131633&cm_re=M4A89GTD_PRO-_-13-131-633-_-Product.
Between the two, I prefer the PRO/USB3 version, as it's only $10 more and provides 2 x USB 3.0 ports.
You might also want to consider the Gigabyte GA-790FXTA-UD5 at http://www.newegg.com/Product/Product.aspx?Item=N82E16813128415.
Yes, the Radeon 4670 is compatible, as the boards have two PCI Express 2.0 x16 slots.
Hope this helps!
