Yes, you'll need to keep 2 cores free to feed the GPU's. You'll be able to run 2X WU's on both of the GPU's which will more than make up for the idle cores

How do I keep the cores idle? Can I run Ati and nvidia card on the same system?

How do I keep the cores idle?
Boinc's computing preferences, Processor usage tab: On multiprocessor systems, use at most x % -- set to only use the number of cores you want for cpu tasks and the others will be available to support the gpu. You can probably get by with only one reserved for v7 but you'll need more for Astropulse.

Can I run Ati and nvidia card on the same system?

Others are running ATI and Nvidia in the same box. I don't know what issues you might encounter. You'll need the option

<use_all_gpus>0|1</use_all_gpus>
If 1, use all GPUs (otherwise only the most capable ones are used).

in a cc_config.xml file.

Actually, he will not. That is only needed when you have 2 distinctly different models from either Nvidia or AMD.

When there is one of each it will use both just fine.
