No, I would say it is about the same. So you're looking at about 2.5GB for your 5 clients and then 1GB for the
OS putting you at 3.5GB total usage. However, the big change with Cataclysm was the introduction of DX11.
DX11 uses much more video RAM than DX9 does because it's shinier and fancier but will most likely give you
better frame rates until you start running out of video memory in which case... you may see artifacts, probably
a large drop in FPS, and/or stuttering.
