I have a box that has two GTX 460s in it - thing is they are different builds and
also have different memory configs - what kind of issues will I have - if any
running with this configuration? (they will not be SLI'd)

here are the two cards:

So long as you don't run more than 2 w/u's on each you shouldn't have any problems.

Cheers.

pull off the heat sinks and count the memory chips. if they are the same i would bet you could unlock the extra memory by flashing with the other cards bios... you just need to unlock the wider bus which is already there.

i unlocked a my 465 to a 470!!! wider memory bus with additional memory plus extra cores.

That's extremely unlikely with the 460's.

BOINC sees the video cards as two separate devices. The estimated time to complete a WU may be an average of the two cards (over time), but there won't be any problems. As previous said, 2 w/u's running on each is the sweet spot.

If you decide to run SLI for gaming, consider under/over-clocking the cards so their core clocks/memory clocks are the same. This will give you a more consistent framerate.

Really nice workstation you have there!
