You must have had some serious stuff installed to exceed 2GB at 1920x1080 being that I only use 2.2GB including caching at 2560x1440 with 60 mods installed (from the thread on the PC forums).
I don't think saying that 2GB can be exceeded is that useful - of course it can but without knowing the exact mods used it doesn't really mean anything. Your mods might have exceeded 2GB but the OPs mods (or the mods he wants to use) might not. It's probably possible to mod it to the teeth and exceed 3GB but that doesn't necessarily mean that it would be recommended to a Titan/6GB 7970/4GB 670 or 680.
All of which is really quite moot as I agree that he should get a 3GB 7950/70 anyway as it's cheaper and faster and has more VRAM as well which essentially does take the debate out of the question.
To the OP - make sure you install RadeonPro if you get one as for me Skyrim was unplayable without it though that could/probably be Crossfire related.
