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.

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...

Not a miner.  An investor, speculator, and enthusiast.

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
beyond

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.
