GTX 760 - Why can't it really utilize 4GB?

I'm looking to purchase the GTX 760's and upon conducting some research, it appears that unless I am doing an SLI, getting the GTX 760 4GB as opposed to 2 GB is a waste of money.

Why is it that the 760 can't fully/effectively utilize 4GB?

In addition, what are factors are important to look at in making such determination?
(For example is memory bandwidth and memory interface width relevant is making such determination? What are some other specs that I should look at?)

Thanks in advance for the help.
 
Solution
Because it isn't fast enough, SLI is the way to go, and if you SLI you can get up to Titan performance, or you could look into the R9 290X coming out in a couple weeks.
It's not that it can't use it it's that there is no need for it. The only way you could possibly use 4 GB VRAM right now is to run 5760x1080 with AA maxed out. With a single 1920x1080 monitor you just don't need 4 GB of VRAM.

The best thing you should look for is benchmarks at the resolution you will play at.
 


It is that though, the 256-bit bus just can't handle it. Now the R9 290X's 512-bit bus on the other hand...

Also the 290X is just as fast and faster in some cases than a Titan and 400 dollars less

The GTX 770 is 256-bit, but seems to be fast enough to handle the 4GB, so what other factors besides the memory interface width is important?

Also, I read that 2 x 760's 4GB SLI is just as good as the GTX Titan. How is this possible?
