I'm wondering if I should wait longer to upgrade or not. I'm playing at 1080p 120hz and 2GB of VRAM is starting to become limiting. I'm having to put games on lowest settings to maintain 120hz now and if SLI isn't supported, I get screwed over. Any thoughts? I'm also going to have to sell my 690 to afford a 980ti, so that is another issue I'll run into if I do wait.
