Use of GPUs adds much to the research possibilities, however, not all our computers are equipped the same, so if we want to use a GPU for a project, we must also declare that project off limits in BOINC on the computer that has a miniscule GPU.

Main machine has an NVidia GTX 560 338 cores, 1GB RAM.
Laptop has an Nvidia NVS 135 8 cores, 128MB free RAM

Seti, GPUGrid, Milkyway are just of a few projects that will use Nvidia and/or ATI GPUs to speed processing, yet, I must also BAN these projects from the CPU on the laptop. YUCK.

So I am HOPING for a future update to BOINC to allow us to select on a HOST basis, rather than on a PROJECT basis whether we want to use a GPU

Can already be done with Boinc 7 with the <exclude_gpu> cc_config option:

Client configuration

You also have four different venues available, (ie, Default, Home, School and Work) and have four sets of Computing preferences available, as well as four sets of Project Preferences (at each separate project),
so you can move your Laptop to a different venue and just make a separate set of preferences for that Laptop, ie, by setting Use NVIDIA GPU to 'No' at each of these projects.
