It seems that although many people are having problems with the A7V, there is always someone else who has encountered it and knows a simple solution. So don't discount it just because you see it cropping up a lot here. I think its popularity is quite an advantage, there will always be someone who knows what you are talking about if you have a problem. My system works for hours, but not forever...then again I'm overclocked to the max, and running a little hot (Majesty cooler, DOH). Just buy a quality cooler (coolermaster seems reasonable) and go for whatever, make a choice and be happy with the process of ironing out your problems.
