Choosing between the following, which would be the better choice:
2 nVidia reference design GTX 970s from Best Buy, bought on sale(when it happens again), $700 shipped
link to cards
or
1 EVGA GeForce GTX 980 Ti 06G-P4-4992-KR 6GB SC GAMING from Newegg, $659.99 shipped(it appears to be a reference design, though I don't know if the quality is as good as the ones from best buy)
link to card
This will be for brute force, large dictionary single 7zip hash attack, maybe some mask attacks as well. It will take years to crack this, I expect, so I'm in it for the long haul. The cards will be migrated to my main desktop when I go to next gen cards in a year or so.
With my current setup, I could add at most 1 more GTX 970 down the line as prices drop, however I could add two more TIs if I wanted to, though I doubt I would ever have that kind of money. This would be my setup for quite a while.
Getting the TI would be a big investment up front for me, while I could get just one GTX 970 now and get the second down the line. From the benchmarks I looked at, the TI looks to be faster for MD5, but I couldn't find anything for 7zip.
Thank you for any help.
