  1. It'll probably only run at half bandwidth.

    But it really doesn't matter because your s939 cpu will never keep up with half a 5770.

  3. It really depends on what processor you have installed on that motherboard. With my old ASRock 939Dual-SATAII board paired with an X2-4800+ CPU, I could run an 8800 GTS-640 without issue. You probably wouldn't want to go much higher than that (and certainly no higher with a lesser CPU).
