Thank you :) I have indeed read that review (and many more) and with your help I am now confident about my 2x Gigabyte GTX 760 4gb plans in conjunction with the ASRock Z87 Extreme 4 mobo I was recommended over at Tom's hardware.

According to http://www.tomshardware.com/reviews/geforce-gtx-760 ...

Wow thank you glimpse, very informative! I hadn't even thought about cooling.

I'm having a hard time finding none-OC cards but Gigabyte 670, 760 and 770 seem to all use the same Windforce 3x coolers. Do you think they won't suffice?

Prices;
760 2gb - 230 EUR
670 4gb - 285 EUR
760 4gb - 285 EUR
770 ...

Ah wow I didn't know that, thanks guys. Will evaluate..

Actually, let me follow up on that.. what gets cached in the VRAM? Textures (compressed?) but what else? Polys?

Maybe I'll just add 50 EUR and get a Gigabyte GeForce GTX 670 OC 4GB or a Gigabyte GeForce GTX 760 OC 4GB instead. They're the ...

Thank you I ended up ordering a 760 2gb for testing purposes. If I need more speed ill get another one and if I need more memory ill get one with more of that. Will post here with findings!

Hey,
I'm considering getting two GTX 760 cards and a 750W PSU to start getting into Octane.

Is two 760 cards a good choice or would it be better value to get 2x670? Is 2x2gb VRAM enough?

I realize Titan blows these cards out if the water but for 4x the price I'm not sure it's a very future proof ...
