My game freezes my computer...

[DemKin]

Hi guys,
So I just started playing that game and I can't get past the... well first part.
Problem is, the game makes my whole computer freeze. It happens randomly, it just blocks and I sometimes have to wait like 2 minutes for it to come back. I can't do an alt-tab or anything and if I try it too much, the PC will just continue freezing constantly on its own even after the game is closed. The game runs perfectly at max settings when it comes to FPS though, I've got a fairly good computer.
Any idea ?... I've got a GTX780Ti.

OK so small edit : lowering the anti-aliasing from QCSAA to 8x MSAA seems to make it better. I can play 10-15 minutes without freezing, which is... yeah, better. Still, I don't wanna have to go back to desktop every 15 minutes to make the game run again ( 'cause yeah, that seems to unfreeze it ). Nobody on the entire internet seems to have the same problem as I do though, as people are talking about crashing but never freezing... I tried the devs' mini-FAQ but nothing works.
What could cause a GTX780Ti not to be able to run anti-aliasing ? Does anyone have a clue ? This is depressing, I really wanna play this game...

Edit again : looks like lowering the antialiasing to 4x finished to solve it. For some reason my GPU can't seem to be able to handle more...

Do what I'm doing and wait for the new GTX 980 Tis to release and then upgrade to one of those. Reportedly they're going to have 6-8 GB VRAM, 384bit memory and 2816 CUDA Cores. It's suuposed be a 50 percent increase over the Titan Black with games performance wise. But these are just rumours however these reported specs seem likely as the GTX 780 and 980s don't have enough VRAM for running everything on ultra for these new games. NVidia PhysX, ubersampling, anistropic filtering and forms of anti-aliasing are the big killers. Plus we are running these games on resolutions higher then 1080p now and 3 to 4 GB of VRAM just doesn't cut it. Was thing of getting a Titan Z but it's too pricey when I could just wait for a 980 Ti :)

I also have the 780Ti and run into the same issues, with small white/green/black dots covering the screen from time to time. It is not a video RAM problem since it also happens with reduced texture resolution (open hardware monitor says that max vram usage is 38%).

More serious freezes happen when the voice-over talks.
