Good news. I hadn't looked at Nvidia's most recent driver release, but now you CAN have a Titan and other Nvidia cards in the same computer at the same time. The Titan's driver is no longer separate from the rest.

Nice!
Edit: any thoughts on the 780 GTX? About half the cost of a Titan, and 90% of the performance.

It's fine for FP32 but your DP drops from 1310 GFLOPS with the Titan to 165.7 GFLOPS on the 780. Other than that, it's definitely worth the money for FP32 in comparison. From a power usage viewpoint, TDP is the same on both. The Titan has more cores, but the 780's base/boost clock is higher.
Edit: Though a 7970 GHz Edition beats the 780 by about 100 GFLOPS in FP32 for about $200 less, and you would also get 1024 GFLOPS of DP.
Well, I have one now.

FWIW, it is running at 993MHz, and I have changed no settings.
Question: Where is the setting in the nvidia control panel to change the DP setting? I can't find it.
Nvidia Control Panel
Manage 3D settings>>Global settings>>CUDA - Double precision
Well, that was obvious. Thanks nVidida.
Thanks JPM!!
FWIW, with fan on auto, the card is running at 1045 MHz.
Sweet! So how does the output compare? Was it worth it?:confused:
I haven't done any benchmarking yet. But I can tell you this: I have two nvidia machines on Bitcoin Utopia. (I know, not the best place for nvidia) One has a 590 and a 580, three GPUs total. The other the titan. The titan does about half the credits/day of the other machine.
So it's probably fairly good performance per watt then. :) That machine with BOTH 590 & 580 must be sucking some serious juice! :D
