A single 690 4gb is almost the same as two 680 2gb's in SLI. Games dont fully utilizes 4GB Graphics memory, except if you're using multi-monitors then it will utilize it.

If you are using one monitor, 3GB graphics memory is better. Most of the games spend more than 2GB in 1080P

that brings to question, i was looking up system requirements for Battlefield 4, and said recommended 2+GB of video memory, so i figured, the more the better?

No, you dont add the memory up like that. 2 2gig cards in sli gives you a total of 2gig available video memory. But, amount of memory is only part of the package. Amount of memory alone is not an indication of performance.

considering two 680s will be better than one 690, and i am using a single 1080p monitor(my tv, actually), best to get a second 680? and will games utilize the other 2gb in the second 680?

The more graphics ram the better on one monitor? No. The more graphics ram the better on multi-monitor? Damn YES. If you have 4GB while playing BF4, lets assume its still in beta, you will have no significant increase in FPS, but with more than one monitor, then it will utilize the 2GB+ graphics memory.
