Question about VRAM and Radeon GPUs

[DrSmitty]

Recently i have been doing research on new and good current GPUs (especially radeon) and looking more into VRAM (GDDR5). I have seen many articles reviewing the performance of the R9 290 and 290x both with 4GB of GDDR5. I was wondering if all 4GB of VRAM is necessary for gaming at 1080p ion intense graphics? It seems that it is not, as most games will only take up to 2GB (even on ultra settings) though there are exceptions. I am confused if this extra ram is for intense settings or support for higher resolution? Also i am wondering if the 2GB is enough to handle new games like BF4, Planetside 2, or DayZ even on max settings? If so i may just go with a nVidia GTX 770 instead of the Radeon, although im still undecided on the ingame performance aspect...

The extra memory is more important when playing games in 4k and it helps a lot when doing multi monitor gaming (a game played over 3 monitors) and that eats up a fair bit of VRAM 3gb is the minimum you need for that but for 1080p gaming 2gb is enough and for in game performance it really does not affect things it gets affected when you talk about memory types like DDR3 and GDDR5 and then even performance is not HUGE
