Nvidia GeForce GTX 590 Dual-GPU Monster Graphics Card Launched, Tested

"... each with 512 CUDA cores". So it's a Giga-core machine? Wow.

Giga usually means 10^9 (or 2^30); don't you mean kilo-core?

It's almost definitely 2.0 since all of the other GF110-based chips are.

My question is, does it look like 1 device or 2 to the CUDA driver? If the memory was shared across 1 virtual device with 3GB, that'd be sweet.

Not really surprising, since CUDA isn't a major selling point for most potential customers. The Anandtech review goes into a little more detail: http://www.anandtech.com/show/4239/nvidias-geforce-gtx-590-d...
