I'm debating on whether to shoot for the GTX 770 4gb or to attempt to future proof even more and go with the GTX 780, but I noticed that the 770 runs at a higher clock rate than the 780, does this really not matter due to how many CUDA cores are in each card? Also I was planning on doing a 3 monitor set up all 3 being at a 1920x1080 setup, primarily one for gaming, and the other for a movie or youtube, how will VRAM take into effect?

I suggest going for the GTX 770 4GB. It's cheaper, really good card especially if SLI-ed for future proofing(40% better than Titan). 4GB is perfect for tri-monitor setup, and if I'm correct, that's the Gigabyte windforce 3x edition. Just make sure that your case supports it, because it's 11"as opposed to 10"/9".

This example is a little on the oversimplified side, but it should give you enough to get started. After which, I'd suggest some of the fine articles on sites like Tom's to get more of the specifics.

If you think of your video card like a freeway, then CUDA cores would be analogous to the number of lanes in the road, clock speed would be the speed limit, and memory interface would be the number of lanes for exit/entry ramps...

If you think of your video card like a freeway, then CUDA cores would be analogous to the number of lanes in the road, clock speed would be the speed limit, and memory interface would be the number of lanes for exit/entry ramps. More lanes means more cars can be moving on the freeway at any given time, the higher the speed limit the faster any given car is moving, and then if there's say 2 exit lanes instead of 1, you can have more cars getting off the freeway, same as you can have more cars coming onto the freeway if there are say 2 entry lanes instead of 1.

Again, it's a bit of an oversimplified example, but it should be enough to get you started in understanding some of the articles explaining these things in greater detail.

But in this comparison, the difference is so little that IMHO it's not worth chipping in the extra cash.
