Hey

I am building another 6 GPU setup

I cant decide between the two.

Here are my thoughts:

• I have a sapphire VaporX but I am not happy with its stability, it was giving 750KHS but now It goes sick/dead unless I lower the frequencies to 950/950 which yields 650KHS, haven't tries to RMA it because I think it will hols a prime 95 test.
• At least 3 people I know have the DualX and had to RMA them as they died, so basically right now I am very suspicious towards sapphire cards...
• While my friend can only get 680KHS from the Gigabyte its working non stop with no need to fiddle with it (which is important to me)
  

So which one should I get? any toughts?
