SLI GTX 295 and GTX 280?

Evening everyone,

I know there have been countless threads about "can I SLI (some card) and (some other card)?" but something I noticed recently caught my attention.

In the release notes of the latest Nvidia driver release (181.22), one line states:

"Enables NVIDIA SLI technology on SLI-certified Intel X58-based motherboards with all SLI-certified GPUs."

I hope this is not just wishful thinking, but would this enable me to natively SLI my current Geforce GTX 280, and the Geforce GTX 295 I am planning to buy in the next 2 (possibly 3) paycheques? Or is this simply saying that SLI support is now available on all X58 based motherboards?
 
its stating the latter
You can only SLI two of the exact same cards
the diff. memory and clock frequencies would make it impossible to have them run cohesively.
The ebst you can do is make the GTX 280 a physics driver
 

You should be able to as essentially they're the same hardware with a different sticker on them. Some of the pre-overclocked ones might have a different hardware id, but I doubt it (how it identified itself to the driver).
