Double GPU mining?

[muscles]

hay d00ds,

I have two pci-e slots and an older GPU that I could put in. Right now I'm running a HD Radeon 6770 for mining at roughly 100Mhash/s but I have another PCI-E slot on my motherboard and an older NVidia card that can mine at around 6Mash/s. Anyone know if its possible to mine on two GPUs at once?

not worth it unless you can stick another radeon 57xx or better in there.

just be careful for the BitCoin miner related scam like get 500Ghash/s nonsense.

Dont get too greedy otherwise your greed will cost you

Yeah, I wouldn't recommend you use the other GPU... 6 MH/s isn't even worth the bother to plug it in.  You might want to look at a BTC calculator to see if you will even be profitable with the next difficulty increase, given power costs, A/C, BTC exchange rate, MH/s rate, etc...

Do y'all run CPU mining while you're running GPU mining? I wonder if you're already running a PC hot for mining on your GPU, is it worth it to also run CPU mining?

I don't think it is ... My GPUs run about 72 if I turn CPU mining on my GPUs slow down a little bit (about the 1 to 2 mH that the cpu makes) and the cards heat up to 75

i ran with a gtx465 and two 5830s for a while, no issue other than nvidia and ati drivers dont like each other very much. once it started working it was fine.

also I run cpu mining all the time, easy to get an extra 10-20mh/s on a decent box.
