There, fixed that for you!
Using the stats from https://en.bitcoin.it/wiki/Mining_hardware_comparison (where nobody has updated that first table to include the 7970):
Model___Mhash/s__Mhash/W____Watts
5830_____248_____1.29________192W
5870_____400_____1.90________210W
5970_____740_____2.15________344W
6970_____365_____2.28________160W
7970_____825_____3.86________214W
Those are still good values but only if you have very cheap electricity.
That 7970 value is pure fantasy. Stock clocks it gets 550 mh/s. 1150 it gets 687 mh/s. I guarantee that particular 7970 is a water cooled or completely made up.
Howso? My 1536 shader 6950s get 2.9MH/s at the wall and my 5970s are even more efficient, and that's with 80+ Bronze and a not even 80+ PSU, respectively.
I think he was talking about the hash rate...which is really high for a 7970.
w00t! Just bolstered my mining farm with 4 BFL Singles. Pretty much doubled my hashrate
Which bitstream are you running? 792MH/s is horribly borked, 768MH/s is iffy (I get errors reported in EasyMiner) and anything higher than 816MH/s throttles excessively (I'm running them in a very warm environment). I'm sticking with 800MH/s for now to avoid overly stressing them.I love mine. They are amazing little boxes.
I don't see any real CPU usage (<5%) on guiminer using the openCL miner. This is on a Win7 Z68 system.
Hmm...wonder what's happening with my system then. I searched on google and did find instances of people reporting 100% CPU usage.
Maybe this is a solution:

Will have to try it tonight.

Also, how hot do your stock power bricks get?
There's supposedly a >1000MH/s bitstreamI'm running the stock 832 bitstream. It's summer and I only run my AC when I am at home. If I kept my room at 72F(their recommended ambient max) or below I can run their 872. I hadn't tried their higher two bitstreams because they weren't out when I was testing.
It ended up being ~$575 per BFL Single. Took just a hair under 2 months for me to receive my 4 Singles.How much did you pay? Have you preordered any of their new boxes that are supposed to change the bitcoin world?
It was a big problem last year with some catalyst drivers, but assume you have recent drivers it shouldn't happen. I haven't used guiminer in a long time though. Maybe try cgminer or diablominer and see if they work better?

Well if I were to upgrade the card to 7970 which card I shoud retire; ? 5870 or 6970 ?58XX cards are the most sought after cards for mining. They are pretty power efficient for their delivered mhash. I wouldn't sell it.
.
Neither. You should buy a motherboard that can hold all three.Well if I were to upgrade the card to 7970 which card I shoud retire; ? 5870 or 6970 ?
Any body rate the pool Eclipse
heeee eeeNeither. You should buy a motherboard that can hold all three.
