I have the GTX 680 Mac Edition 2gb. Im looking to get into 4k video. And I want to up the annie so to speak. I am looking at the GTX 780 and it has similar specs, however, it has a lower Base/Boost Clock speed than the GTX680. So What kind of increases can I expect upgrading to a GTX780?
(the gtx780 flashed from MacVidCards for bootscreen and no external power supply)

Here are the specs. Will it be a big jump, or negligible?

Better performance in what? It depends upon what you are doing.

But, in very generic terms, performance should be about 20%-40% better for software taking advantage of its hardware acceleration.

I mainly do video editing. But I will use for some gaming also. Mainly 4k/RAW video editing though.
 
What are you editing in? Research what GPU acceleration your program uses and make a decision then. You could be better off ditching the 680 and running dual ATI/AMD cards for instance.

Check out www.barefeats.com for some benchmarks that may be relevant to you.
 
Hi Korican. You may have seen the Barefeats test on the Nvidia 680GTX compared to other cards, http://www.barefeats.com/gpu680v.html Though it did not include the 780GTX Though it will all depend on the software to be used and how it interacts with the GPU. There will be medium heavy tasks that you won't see a noticeable difference between the 680GTX or 780GTX. From the user's reviews, the performance of the 680GTX was satisfactory in general but the 780GTX I think is also good.
 
^^^^There is a newer comparison here:

http://www.barefeats.com/gputitan.html

that does include the GTX 780 as well as two versions of the GTX 680, the Mac Version and a 4GB version flashed by MVC. IMHO, the comparison of the two cards is akin to comparing the C6 and C7 Vette. Both are good, one is a later design and faster.

For a VERY basic/naive comparison. multiply the core count by the clock. 780 easily wins.
