Hi newcomer and welcome to the Tom's hardware forum.
1- For a gaming rig is better a mobo without onboard video, so, the three options with onboard video aren't good.
2- The best of the other two, is the 790FXTA-UD5, but if u can go with the new 890FXA-UD5 is a very solid mobo too.
3- If u want a big performance in HD u need a SSD, or the new WD velociraptor 6Gb/s.
4- The best chipset is AMD, is very solid and stable.
