hmmm if this is the caseI may lean towards ati, the 7970s would certainly be a bit cheaper and net a lot of the same performance
The 7970 cards have better crossfire scaling in a lot of games anyways. They get better performance in games than sli 680 cards in many cases.

lol i was going to say the same thing, the scale alot better, i want to see how the 685's are going to be, and the amd 7000's are starting to look like a really good deal now adays, a bit cheaper, 3 free good games, very very close with th 680, better multi gpu scalling/ comuting

Cool it looks like I might actually have to try out ATI for once... Thanks!

I am having little success compiling cpyrit_calpp for pyrit.

One Nvidia 260 ~ 10,000 keys/sec
Both 260s overclocked ~ 25,000 keys/sec

I wanted to get a 6870 (not for my current workstation), but now I'm thinking I want to avoid the crap with learning ATI's software and stick with NVIDIA.

I forgot to mention I found a 4850 at work and that is what I'm trying to get working... Arch x86_x64

For the best stock power 2x 680 would be my choice , 690 is still pretty good but less power than 2x680 and less power usage too

2x 7970 you can almost get 2x 670 instead and they would be better.

only good thing 7970 is better than the 670 is higher rez ( more than 2560x cant rem )

getting cuda to work with linux is certainly a hell of a lot than ati with either opencl or calpp, that is for sure. I'm pretty split on this decision right now, I might end up buying on of each and seeing which performs better and selling the other...

I got the 4850 working correctly with CAL++. It wasn't as bad as I thought (once I got it working).

did you go with the 680's?

Edit: didnt read your full post, if you are looking for gpu computing that its nivida rulled, like F@H, the 680 dose outpreform a 500 series and the 7000series , but at such a low margin its a waste of money get a oc 580 before the stock goes away forever. but amd 7000 its betting the 680's in openCL by quite a margin

hmmm im still kind of on the rocks but im looking at getting 2x 680s (4gb) or 2x 7970s. I really like nvidia and I think I might stick with green to make use of my 3d monitor. I returning from deployment in less than a month but I'm about to make a move and have some stuff ordered and waiting for me at home to complement the i7 970 I upgraded too

next looks like I may need a new monitor or a second or third lol to utilize these cards

edit: does anyone know how just one gtx 680 would compare to my current 3x GTX 470s?

If I remember correctly they axed Keplers compute performance for the die shrink, considering AMD is a cheaper option and would perform within 10% in almost all cases and better in computer the choice is clear at least it would be for me.

http://www.anandtech.com/show/5699/nvidia-geforce-gtx-680-review/17


That link on Anand shows that the 680 is vastly inferior to the 7970 and even slower than the 580 in compute with the exception of Shader Fluid Simulation. I'm probably one of the most impartial people when it comes to graphics cards, yes I have 7970s however I was really considering to switching to 680s but the prospect of selling my 7970 and dropping around $150 for roughly the same performance wasn't worth my trouble.

Once OC'd they will perform almost identically on average, typically 7970s will OC higher than 680s but the 680's are faster clock for clock (in synthetics it will always depend about what title you play). The price and Compute performance would really make it worth to you to go with 7970s
