hmm thinking about going 780 3gb instead of originally planned 770 4gb
256bit bus Memory Bandwidth of a GTX680/770 = 192 GB/s
384bit bus Memory Bandwidth of a GTX780 = 288 GB/s
the 384bit is faster so 3gb should not be hindrance on a single 1440p. i dont plan to go beyond single monitor, dont have space and well a 780 gives you over 60fps in every game on ultra except Crysis 3, metro 2033 and FC3 tough FC3 is very close to 60 and. i have the money, its like 430~450eur for gb 770 4gb oc vs 582eur for gigabyte 780 wf3 oc (7eur diff between stock and oc wf3 version). i would not go with evga as their cards cost 650eur+ for the same clock

my question is whether 3gb of 780 would be sufficient. i mean if i look at memory bandwith it looks that 780 can process 40-50% more data per second so does this mean it would not hit vram wall on single 1440p before a 770 4gb would hit the wall in same scenario, because 780 has 384bit bus?
my friend had over 3gb vram usage in max payne 3 @1440p so thats why i am asking if i am to fork 582eur for a card smile.gif
