I just returned to Einstein and I am running 2-750ti's. Standard app under windows 10. Computer has been on the project about 2 weeks now so RAC is still climbing. At present I seem to have about 130,000 RAC (Free DC). I will report once the RAC levels out.
Well it seems that my two 750ti have leveled out at 165,000+ RAC.
I don't think so :-).
Each task (in the main) is taking less than approximately 3000s elapsed time. A 'back-of-the-envelope' calculation, assuming no CPU task contribution, says your RAC should finally reach around (86400/3000)x3465x2=200K. Of course this assumes 24/7 operation and no slowdown from other things your computer might be doing.
You seem to have two groups of results. There are a number that finish around 3000s and also another group that finish around 2800s. Maybe one GPU is doing a bit better than the other?
So I tested the 750ti. I was limited to the low profile card due to the height of the case as well as the fact that the pci-e slot was at the top of of the board so I could only use single slot cards.
I tested it for 1 week (stopped due to heat complaints. I will return to it) on a Linux mint 17 machine as well as a windows 7 machine. I averaged 720 seconds per W/U on both machines. It got only to a few thousand RAC before I killed it. The Linux machine as well as the windows only seemed to allow 1 W/U to crunch at a time. I will need to investigate further once I find a place to relocate the computers to.

Surely the 720 secs is a typo? You should check numbers like these so as not to mislead people. The Windows machine has no tasks still showing in the online database. The Linux machine has plenty (237 tasks total for all types) but all show a status of "completed, waiting for validation" but are all past the deadline. This is an obvious bug in the latest enhancements to the display of task lists. If you check any workunit ID you will see that your tasks were "Timed out - no response", rather than waiting for validation. With no actual completed results, it's not possible to check the true crunch time. It doesn't look like the Linux machine returned any GPU tasks in the last couple of weeks.

Both those hosts are dual core. The 750Ti cards have enough GPU RAM to run 2 concurrent GPU tasks, but I suspect you wouldn't see much improvement (if any) if you were able to do so. Both CPU cores would be required for GPU support. The Linux machine shows as having 2GB RAM, the Windows machine 3GB. It would be wise to have at least 4GB RAM if you plan to crunch the current task types at Einstein. I imagine the Linux machine (in its current configuration) would be badly affected by continual swapping from lack of physical RAM.

I wish you were right Gary, but it looks like it leveled out at the 175k range to me.

It's not fully stable yet. There are several reasons to anticipate a further rise.
You need at least 30-35 days of uninterrupted crunching to reach a plateau. You didn't start until around 22nd June.
You didn't seem to reach full production until around 24th June.
You had some sort of glitch around 29th June and again around 12th July. These will add extra days before the plateau.
The elapsed crunch time is certainly still averaging 3000sec or less. So provided you are crunching continuously and are not producing invalids. you will get to 200K.
I think you may need to wait till the end of the month or early next month to see the full value.

My only concern with the low profile card is it does get a good deal warmer than the full height card.

Have you overclocked those cards? I see you run Windows so there could be a chance to gain roughly extra 10% by raising the clocks a little bit.

Don't try Windows 10 Creators

Don't try Windows 10 Creators update. It killed my RAC. I revered my OS.
