Looks pretty solid overall. I don't have any specific issue with that mobo, but it is a bit limited in the OC RAM speeds it supports compared to other boards in that price range. The reviews seem generally positive with the odd DOA, but that's to be expected with all motherboards. You might consider the ASUS below if you have concerns about the Gigabyte board:

As far as the video card is concerned I would recommend stepping up the the 7850/7870. You might consider waiting to see if the pending release of the 660ti next week by nvidia has any effect on AMD prices, but both cards can already be had at a reasonable price. The 7850 has performance about equal to the 6950 at stock speeds, but much more potential if overclocked. The 7870 is simply a superior card. AMD made pretty substantial improvements in both power consumption and DX11 tessellation performance with the 7000 series. Here are a couple to consider:
7850 -

7870 -
http://www.newegg.co...N82E16814125418 - $280 after rebate
At 1920x1080 you will probably be happy with the 7850, and your board will allow you to add another one at a later date once the prices have dropped.
Also, you probably won't need an aftermarket heatsink unless you plan to agressively overclock your CPU. Being a new build, you're not likely to be CPU limited in any games right now so there probably isn't a need to OC unless you just like big benchmark numbers. Keep in mind that adding an aftermarket HSF will void the warranty on the CPU. If you find that you're bottlenecked by the CPU at some point in the future then you could always add an aftermarket cooler at that point. GL.
