I only get 5-30 fps on my tri sli gtx 570 setup on ultra.
So obviously I need to spend a massive ammount because it wont run well on my 2000$ computer.
I'd hate to see what it runs at on a single card budget setup.
Is that a joke or something? A single GTX 570 could max this game. It's obvious to me that there must be something wrong with your setup...perhaps too many background applications. Even my older 1GB Radeon 4870 got great frames at 1920x1080 with pretty much max settings. And this game is not really going to scale Tri-SLI very well, if not at all, especially at anything lower than 2560x1600 resolution. Elderscroll/Fallout games are hit-and-miss with Crossfire and SLI.
And a $1800 notebook is not going to run the game better than your current system, but if you really want a notebook for that much, one of these should fit the bill fine:
