Run two copies of the GPU2 client, one with -gpu 0 and the other with -gpu 1.

Nah, any drop in points should be minimal (<100PPD) for each GPU.

usually if i'm adding a new card into it.. i uninstall drivers and clean it up. then add in the new card, reinstall drivers. then set up the new client.

for the new client, copy your current gpu client and rename it to what you like. usually best to keep it simple.. then delete: work, unitinfo, myfolding. queue, and configuration files/folders.
and redo the configs but this time add -gpu 1 to the additional parameters and shutdown and restart it. then for your first one.. open it up and add -gpu 0

Nice thanks bro! I have been told sooooo many things. That's why I needed a pro to tell me..everyone is saying that I need to do crazy things to get it to work or to get max PPD out of them. I don't mind giving up 200ppd on both cards to be able to get both cards up and running.

I might need some more help when I go to set it up...looks like I need to go to vista first. xp will use both my cores to run both cards...sigh*

You are only going to use one driver. So the driver you use has to be compatable with both cards. You should be able to use the 177.35 + INF file if you can't find a better driver. I used the 177.35 driver on 6 different cards, worked great on all of them.

i heard that the new 180.60 beta drivers drops core useage for gpu2 like mad.. so you might want to try those out. this is for XP. with vista.. iirc, it was hueristic that said it helped him drop core useage.

+1 nafljhy, 180.60 drops CPU usage to 5% for XP at the cost of 2-3% ppd. I've got it running on 3 rigs with no problems.
