GTX590 the best?

[tricky]

Just thinking about a machine specifically for RT GPU. Am I right in thinking that the GTX590 is still the best card for RT GPU?

If so, where the heck can you get them from???? I can see the 580 cards at Scan, but they have far fewer CUDA cores.

I am contemplating building a Quad GFX card machine, and 4x590 would be the best way, right?

I think I am ging to struggle to find the GTX590 cards, so might go for 4x 680 or 670 cards instead.

How might I cool these cards? I presume a motherboard will not have space for 4x cards with their stock coolers. A water based system? Yikes....

Umh... Get TITAN ? Titan > ALL atm so...

4x TITAn = 6gb each cards 1 titan = 2x 580 GTX or so.... so titan win.

Yes - just looking at these titan cards. Maybe two of those...
(all theoretical at the moment - looking at options)

GTX 690 is as fast as Titan since it has two gpus, but not sure how many you can put into one machine...

690 has 2gb ber core where as titan has 6gb per core... Sooo

yeah for sure, if I'd spend the 1 grand + on a card it be Titan. Better yet, 10 titans
