So SLI seems to be the most cost efficient method i.e. double the power per physical box... nice thing is you can probably upgrade those GPU's across a few generations without upgrading the rest of the system since the PCI specs don't change much and power draw tends to decrease with newer cards.
I mean, it's not cheap but I'll assume the dollar per flops ratio is way higher. On Fri, Oct 3, 2014 at 11:43 AM, Ed Manning <[email protected]> wrote: > Ditto. total gamechanger.
