I am looking at building a Phenom II 940 rig and am wondering in real world performance how effective is the SB750. I was looking at this motherboard DFI LP UT 790FX-M2R http://www.newegg.com/Product/Product.aspx?Item=N82E16813136041 and it seemed to be great at overclocking. I have used a ASUS M3A79-T Deluxe on a Phenom X3 and it seemed nice but i toped out at 3.2GHz. Thanks in advance.
