...To me, particularly considering the additional 1Gb GDDR5 on the Ti version, that's worth the additional $40 outlay.

I think that may be the ticket for future proofing in a way. I remember when the projects required 512MB RAM or they wouldn't run right. At some point it's not inconceivable that projects would require X amount of RAM or you can't get a WU - and the Ti version might win out in the long term.
Of course if you rotate your hardware every year or two then that's probably not a big concern yet.

Screw it. I just ordered one: http://www.evga.com/Products/Product...02G-P4-3753-KR
It will replace the HD 6570 in my HTPC - about double the GFLOPs and 4-5x the performance on most BOINC apps for the same 60 Watts!

Way to step up to the plate!

So, for $124, you're saying this Zotac would be a safe bet for a basic cruncher for things with wimpy power supplies? As long as it has even PCIe 1.1?

Correct. Or this Gigabyte one: http://www.newegg.com/Product/Produc...82E16814125503 Same price (almost) but just a little faster.

So it would appear, from a power required standpoint, I would be better off to sell my 3-570s and my 560ti 448 core and replace them with 750s or 750ti's. The power draw decrease is dramatic, which would be nice. The specs I've seen show more cuda cores on the 750ti, but that doesn't necessarily equate to better crunching ability. Do we know how the 750ti crunches by comparison to the 570? Just looking at PrimeGrid's Fastest GPUs seems to indicate the the 750ti is considerably slower than the 570. That isn't necessarily a deal killer, just curious.

Edit: Comparison from PrimeGrid. I have no idea if the 750ti is oced or not, my 570 is to 850...but the 750ti is still only 60 watts.

Well if my math is correct, based on those numbers you posted the 570 potentially uses 3.65 times more power to do 2.42 times the work. But that is only one project. My results most likely may not apply to say, a project like Collatz.

#5 needs more input...

Well, here's some other projects for comparison. Someone else do the math. Apparently it sizes up to a 480, but at only 60 watts. I guess it boils down to whether you can accept less cpd to save on the electricity. Of course if you put 3 or 4 single slots (if they become available) in a system you might not really be saving much.

Sure you would. x3 750 = 180W max. 570 = 219W max. That's the equivalent of a 40W light bulb. Plus, those 3 750s will out perform that single 570. Another side benefit is redundancy. If a 750 fails, you still have the other two crunching away. Not so with a single 570.

The only drawback is the MB. To handle 3 of any kind of GPU requires a MB with dual 4-pin or 6-pin 12V Aux. connectors. Just too much current draw for a single Aux.

If the 750Ti in the 570 comparison was a base model, then you could very easily require only 2 of them to equal the 570 for a whole let less wattage. Some of the OC models are 20%+ above base clocks out of the box, and can still be OC'd further, though these usually have a 6-pin plug added just in case. You do not have to plug anything into it if you don't want to. The heatsinks on the 750/750Ti are overkill so it will still run cool even if you jacked it up to 1300MHz.

so basically the math says, if you have the slots available, you can replace your 570 with 2 or even 3 750Ti's, crunch faster, produce less heat and save money on your bill all at the same time. Oh and it'd be quieter too.
