So, I was playing around with EVGA's Precision software. As you can see in the image below, WoW managed to chew up to 1250 MB of video memory of my Gigabyte NIVIDIA GTX 580 Super Overclock's 1.5 GB.
I wonder if anyone has seen WoW chewing up more dedicated video memory than that at resolutions of 2560X1440 or 2560X1600.
Looks like that 1.5 GB of video memory is BARELY adequate even for an ancient game such as WoW with a retarded graphics/video engine.
P.S: My FPS is capped @57. Absolutely no reason to go over 60 FPS.

EDIT: The maximum video memory I have seen WoW chew up is 1275 MB in the same settings, i.e. 1920X1080 ULTRA.
