It looks like I may have a chance to replace one of my computers, using a GTX 560, with a newer computer using a GTX 980, although not very soon. Where can I find information comparing the double precision capability of these two graphics boards?

Thanks - that looks like enough information to decide that the GTX 980 probably has a little more double precision performance, even if it doesn't make that definite.

A gtx 560 has 384 shaders while a GTX 980 has 2048, that means it will be roughly 5 to 6 times faster on the same workunits. The 980 has other advantages too, ie more on board memory, faster processing, bigger bandwidth, etc, etc which should give it even better performance. In short what you are considering is a BIG update!!

Correct for single-precision performance, but not for the double-precision performance I was looking for information on.

if you want to upgrade your graphic card based on milkyway performance you may want to consider taking an amd card as those are far superior for this project

I want to upgrade the card, but Milkyway is not the main BOINC project I intend to use it on. The main project works much better with Nvidia cards.

Generally speaking AMD cards do better at Milkyway and Nvidia cards do better at Seti. So I've found anyway.
