Rig 1: 2x XFX 290x and 1x Sapphire 290 (each 290x hashes at 940 with 3% reject rate, i was able to pull 980 each card but reject rate started to climb) and the 290 hashes about 880
Rig 2: 1x XFX DD 280x and 2x Gigabyte 280x that were DOA (awaiting return so I can replace) - so this rig is out of comish til I can replace the 2 gigabytes, thinking about just running the single XFX however
I ran out of money so I had to go cheap on the PSU with the Raidmax 1200AE Gold on each rig

Reading alot of reviews saying these fake gold rated PSU's are not ideal.. but It's all I could afford. Hopefully they'll last til I break even on my investment and start earning money to replace them with better quality units.
It sounds to me that you are doing scripts instead of SHA-256 so I would suggest you mine Dogecoin today as they are at 138% profit margin projection for the day. The projection not counting your electricity at all because I don't know your watts or what your electric company charges per kilowatt hour so your projection in Dogecoin for the day is to make $42.36 USD versus right under $40 for Namecoin or next of about $30.50 with Litecoin.
