I have 2 x AMD 7790s on a m/board with dual 16x PCIe slots.
I have coupled this with a minimal 4Gb of memory, and old mechanical hdd, and a minimalist dualcore E4600 CPU.
The idea behind this was to have a code crunching platform for the GPUs and nothing more ATM.
I have amended the boinc data file so that both graphics cards are recognised and seem to be working well, but I don't want the CPU busting it tail (futilely) crunching data, but rather leave it to the reasonably beefy GPUs.
I have been experimenting with the CPU settings, but I was wondering if someone knows the best way to configure things such that these graphics cards are optimally supported, whilst not caning the tail of a weak little CPU and chewing up excess power in the process.

How would you optimise my rig?

Looks like you're getting Collatz and MW. I know those projects can select CPU and or/GPU projects. I actually don't know of a project that doesn't allow for processor selection.

You should be able to de-select 'Use CPU' for each so that the only work done is on the GPUs.

MW: You will want to run several tasks at once to keep it busy as there is some CPU only work done at the end of each bundled task. I ran 4x at once.

Collatz: There is some optimization done with the gpu config files that will speed up work quite a bit.
