Best 8GB RAM to use with Asrock 970 Extreme4 + FX8350?
The price can't be over 70 euros.
This should be the best RAM in my opinion. It is fast, it is small and it looks awesome (might be a factor for some). It should work awesome, just get it. It is a good one

Other Option :
1. Corsair Vengance : http://www.amazon.es/Corsair-Vengeance-Memoria-DDR3-PC1600/dp/B004CRSM4I/ref=sr_1_420?s=computers&ie=UTF8&qid=1375285177&sr=1-420&keywords=8GB

These are some of the best choices. The reason that I did not recommended the Corsair Vengance at the first place is because it's heatsinks are quite big which can cause clearance issues with some CPU Coolers, which is why i recommended the G.Skill Sniper. It is an awesome small RAM which is a very good performer.
I hope this helps. Is there anything else I can do for you? I would be happy to help.
