Validation Errors on Specific Computer, all from GPU Tasks

(moderation:
I have a specific (piece of junk it appears) computer I'm always having a problem with while running einstein@home, from the first day I bought it unfortunately. I'd like to get better at determining what's wrong. As it's always something different.
It has a GTX 560 TI, a GTX 660 TI, and a GTX 770 in it, i7-3930k. Running Windows 7. Good quality PSU, Memory, etc. Except for
the junky AsRock Mobo, which is probably most of my problems.
Bunch of questions:
a) Why isn't the GTX 550Ti graphics card being used "anymore"? I can't figure out why, maybe unsupported now? Is there a minimum memory requirement for the project GPUs now?
b) More importantly, most of my tasks seem to be failing verification. I cannot figure out why. I thought I knew how to tell which graphics card they were running on, but from the tasks web section of the site, I cannot seem to determine that. I just see it seems to have exited cleanly, but failing verification.
Machine is 12623094, example task is: 816811538
It seems SOME of the valid tasks are from the GPUs. But many are not.
c) How can I tell when a task isn't validating which GPU it was run from?
d) Are there any more CUDA tasks? openCL causes me nothing but problems work task wise it seems. My machines ran a lot better with CUDA.
Are you running 1 task at a
)
Are you running 1 task at a time per card? Excess heat could cause validation errors especially if there are all of the three cards installed on the system. I can't remember if the GTX 5xx series is supported anymore, but if that card has 1GB RAM that might not be enough.
It would be best to test the cards by installing only one card in the computer and see how it would run. Then if it run well, replace it with the other one. If all run well alone then try a setup with 2 cards.
There's not currently CUDA app available. And because of that, I think this next thing is also good to mention. Earlier when there still was CUDA app those 6xx and 7xx series cards where great. With the current opencl they sadly lost very much of their computational power here.
If you would like to think about alternative options in the current situation... I could promise that by replacing all those three cards with ONE card - a little bit newer Nvidia GTX 960 ... or a AMD 270 / 270X / 280 - you would get more tasks done and that would require also less electricity. I believe there would be a real chance that investment wouldn't cost anything if you also sold the three cards. But if you prefer running the current setup and make the best of it... I know It can be interesting too.
