I have never seen a 120hz lightbost monitor in action, but i hear about it being a game changer you can't comprehend until after you try it, which is exciting. So a lil hyped.
If i go 120 hz - the 770s should be fine.. but what about 1440p? I heard even some 1080 games use like 2.5 gigs vram..
If I were you, I would go ahead and grab a 780, no matter what, it has 3 gigs of RAM, it's GK110, and you don't have to deal with driver issues. At 500 bucks right now, you can't go wrong. If you are only going to stay at a 1080p monitor, don't forget the R9 280X/ HD 7970 are sitting at that $300 sweet spot, and each have 3 gigs of RAM. In your case, the 780 would still be a great option because you can take full advantage of that 120hz monitor. Personally, I don't think the 770 should be an option for you right considering the 7970 is almost as fast for 30 bucks less.
Option 1: Grab a 7970 and save 200 bucks.
Option 2: Grab a 780 and be really happy for the next 3 years.
It's your call, but like I said, I would just grab a 780, and in the future you'll have a multi card solution that works.
