I have a 750ti and 470 in the same Windows 10 rig, once the Foldathon is over I can run a few work units of the projects you are interested in.
+1 virtual rep first and foremost
I'm definitely curious as to how they'll perform, although a part of me is thinking I might as well just look into the prospect of a single RX 480 per setup as after a bunch of math I realized with a single card in each of the two setups I could stick to three of the goals I have with this BOINC rig...
- dedicated threads for the two CPU POTM's
- an even integer amount for each project (instead of having threads flip back and forth between projects), and
- a minimum of four threads per project (a subsect of this goal was to increase overall PPD/RAC for my main projects, as with my more recent project configs I've had it so that my bigger ones were usually only having two each)
Sadly some projects didn't quite make the cut when I looked into those three rules being fulfilled (I'll be dropping PrimeGrid and Seti@Home Beta as regulars, for example) but at the same time being able to go from three projects up to eight or nine (and having a reasonable amount of work done for each) is one I'm liking the sound of.
I'm definitely curious about the RX 470 and how it might compare to the data (someone, ack forgot their name!!) was posting for the RX 480.

Also remember those Intel boards cannot accept a full length 16x card w/o a riser cable.
I had a feeling that a pre-GCN card wouldn't have quite the same staying power. Oh well, they'll get to live in the shadow of my benching rig for a time when they can be truly pushed ^_^
Main reason I had contemplated the HD 6850's in the first place was I already had them, but if it's going to be a case of a decent amount of heat being produced for little in the way of actual work being done I'd rather look into spending the money on new gear (even if the overall goal of this rig is to have 60 threads of cpu and two gpu's across multiple projects for hopefully less than $2k CAD before the case and watercooling is factored in)
As for the bit about not fitting, they'd still work in the 8x slots, wouldn't they? Looks like those slots are open backed, not to mention have locks to hold the card in place.
