Yes, just on the GPU slot, there are no BETA projects currently for CPU's.... you know when you ahve a BETA - it is project ID 8900 or 7663 - and by having the beta flag doesn't mean you get them - just means your card is eligible, in case some are available when you request a new WU.
Make sure you add the BETA option to your GPU slot - see the FAQ for more info. This will get you access to the beta projects. Right now it varies on project and card, but the AMD camp is squeaking out a bit ahead. But, this is all with Beta projects. Once everything is finalized, be interesting to see where things line up.
And you are correct, the FAH client is not currenly "optimized" for the new NVidia cards. Hopefully they update soon.
