Re: Will the ATI Radeon HD 5970 be bottlenecked by a Athlon II tri firstname.lastname@example.orgGHz?
No, it will not be a massive bottleneck at all. For games/folding, you will get better performance with an Athlon II x3 and a 5970 than with a Phenom x4 and a 5870, that is until you get to games with a lot of physics processing, but even then, the CPU will still be good. The only thing I would say to consider is a GTX580 over a 5970, as it uses less power, is smaller, produces less heat and has Physx. It will also be slightly cheaper, and have the same performance in games and similar features, but with extra performance in games with heavy tesselation.
The last point is, at the moment, just marketing jargon, but more games are starting to utilise multilayered tesselation because both Nvidia and ATi are focussing on it more.
Either way, you will get a card that is plenty for your need. However, what power supply will you be using with all of this?
