Cant say much more than the Asus 770 4GB rocks! Just upgraded(not sure it is more than an upgrade) from the 2x 560ti 2Gb's to the 770 4gb version! Must say Prepar3d looks and runs smashingly!!! Now I have two 560ti to flog...
Hi Brian, yes my P3D wont use all of the VRAM but who knows i might get a couple of monitors... BF4 however uses about 3.3gb of VRAM so it helped over there...
