Ok, So I have two 7770's coming to me this week that were going to replace my single Sapphire 7870 that I was going to return. I also have a single 7770 coming for my Work PC. Change of plans now (I'll get it figured out soon enough!)...

-- Two 7770's will be exchanged for 1 Gigabyte GV-R787OC-2GD 7870 with 1100 core out of the box and placed in my Home PC running 3 GPU WU's.

-- Single Sapphire is going back (won't OC at all & has issues at mfg specs) and replaced with the above mentioned setup.

-- Single 7770 for Work PC stays as planned.

So I will have two 7870's in my Home PC running 3 WU's each for a total of 6 WU's on that system. Should be good for 800,000+ PPD WCG easily

And then 2 WU's running on the 7770 for another 150,000 PPF WCG.

So hopefully by SC Week I'll be doing closed to 1 Million PPD WCG
