Good evening. I'm an avid PC gamer, and I'm presently using an EVGA gtx 780 card to push the pixels on a 1440p monitor. The GPU has 3gb of vram, and so far only Skyrim has gone past the 2gbs usage of vram, and that's with all the sliders at Ultra and the HD patches installed, as well as a lot of large mods. Just recently I read a very short blurb about the ASUS ROG dual-760 card, capable of out-performing both AMD and nVidia's top of the line GPUs. But they used 2gb versions of the 760, so only 2gbs of vram will be available for use, and the reviewer said that it would be perfect for single-monitor gaming, but may not work so well for triple-monitors, etc. I also know that when I had a GTX 580 1.5gb GPU installed, I was able to play Skyrim with the HD patches and a few mods and there was never a glitch or stutter. WAT? I think that I, and a great number of other non-experts in this matter may be confused about how vram is used in the PC for displaying those gorgeous pixels. So I wanted to find out if that's the case, and I wondered if anyone here can either give a short explanation on how vram works, or at least a link to where I can go to learn more about it. With the Ultra-HD monitors being produced now, (I've seen a Romanian review for a 3840x2160, 28" monitor selling for @ 600 Euros, for instance) I would think that the VRAM issue will become more prominent. I mean, is it just when multiple monitors enter the equation that VRAM may be a bottleneck issue, or is it the total usage alone, or...? Thanks for any help with this issue.
