300 watts

...i didn't notice this before.
and then you can use 4 of them in sli...

Yes. 4x GTX580 on an overclocked SR-2 with dual X5680 CPUs. You'd need a 2000 watt PSU. Or more likely, dual 1200watt units.

Not to mention an extra air conditioner...

This article sums up my findings very nicely:

Personally I would go for an GTX 470 if you want it all in one package. 1GB RAM of RAM is not worth trying though except very easy scenes. Generally I found that textures eat up more memory than geometry.
If you plan to do serious GPU computing with Iray make sure to have a steady airflow through your case, it will be very noisy and hot. Also do not expect wonders from a single GPU coming from the 980X and Maxwell that you are probably going to compare it to. (that's why they usually use a triple or quad SLI GTX 480 setup to render their "scenes" in their demos... )

Thanks for the article link, Ben.

Well, after some more research I have just ordered my new card. I got this one:

Tom's Hardware said some good things about it (less noise and heat).

400W+!!! with an i7 980X @ 3,7GHz ...ok, i think my HD5770 is fast enough!

...but congrats to your new engine!

Are you planning to use with any GPU renderers that shall not be named?

Interested in compute performance...

[Bubbaloo]

Yes, I'll use it with Iray (if it performs OK). Expect some rendered comparisons between Maxwell and Iray as soon as I get it. Right now, Iray is the only GPU renderer that interests me because I have experience with mental ray.

The 580 is a good choice Brian. I don't think you would need to overclock it though, since it's basically the top of the line and you generally overclock to get more performance out of a cheaper card for things like gaming. At factory settings, the 580 runs cooler and is more energy efficient than the 480.
