How much have you got to spend? Are you an OC'er? I think regardless of the answers to the questions you can get a better board. Answering them however, would help me select the best for your situation.
If you have $200 to spend on a motherboard and you are an OC'er I recommend the Asus M3A79-T Deluxe. While for a processor I recommend the AMD Athlon 64 X2 5400+ BE. Although it seems cheap, with the board recommended above, you should be able to easily hit the 3.4GHz mark.
If you're not an OC'er I highly recommend you make the switch over from AMD to Intel. If you can't do that then I suggest you get the same processor listed above, but instea of the OC'er motherboard, get the Foxconn A7GM-S 780G.
I am currently running the GIGABYTE GA-MA790FX-DS5. So far as I have seen, it runs great. I have an X2 5000+ Black Edition CPU overclocked to 3.1GHz sitting in it.
AR, any idea of how the DS4 OC's? He could be able to push the 5400+ further than the 6000+. Although I'm not sure on how good of a OC'er the user and the processor are...
Well, considering the 6000+ is running at 3.1GHz already and can be pushed a bit further, it would be a better buy than the 5400+ BE.
I'm not sure of it's overclocking abilities, but there's more to a motherboard then just overclocking. Stability and performance just to name a couple. The AMD 790 is an excellent performing chipset for the AMD CPU's.
