I can't say anything about the gear causing the problem - I don't know. What I have found is that it is seemingly time based. What I mean by that is that I will load the game and start playing with FPS being fine (30 range - which is fine for me i like playing on max graphics) though after around 20-30 minutes this drops to 1-10 FPS. Tested this a couple of times and always after a certain amount of time it seems to go to shit. *Note* - I play with a friend always so maybe the close proximity is bad? Anyway I have done all the FPS adjusting graphics related tricks mentioned here and in the steam post but it seemingly has no effect for me... at least not a lasting one. Prior to the last patch my game ran perfectly. I have an Alienware m17x with nvidea geforce GTX 680M, quad core with 8 threads etc etc. Though again i dont think its a hardware issue since prior to the last patch everything was perfect. EDIT: Since the patch this week they have indeed resolved this issue.
