I'm GOING to build a pc. Specs:
Intel core i5 46xxk haswell
Motherboard for haswell
60gb ssd
2tb barracuda
2x asus oc 660
16gb ripjaw
powercool sli ready psu
sharkoon tauron
cosair hydro series (not sure which one, yet)

You get the point, but I was ... Wondering, purely for hypothetical reasons:
I would of cause use an sli bridge to connect the two 660s... Simple. But, say if I bought an nvidia 630 or something, and used it PURELY for physx processing and nothing else, would it improve performance? I mean, if you had one whole graphics card for just physx and two pretty powerful ones for graphics processing, would it be good? Another thing, if I did connect these gpus up, would I use a three way sli bridge or just plonk the two as an sli and leave the other one on its own?

MY understanding is designating a card simply for PhysX does decrease the load on the remaining card(s) and allow them to do more. Short of Googling, I could not give you percentages, but it is possible to have 2 cards in SLI and a third by itself with no bridge for PhysX.

Just make sure the PSU can handle it all.

It is indeed possible to designate a card specifically for physx. Just going to the nvidia control panel allows you to designate the physx processor. Just make sure it's an nvidia card!
I think you'll want about a 750W-800W PSU for those three cards.

Could you recommend me a fairly cheap psu that will work for me?

The corsair enthusiast series 750w psu is reliable and one of the cheaper 750w psus.

Is there anything a bit cheaper?

Any of the cheaper ones will likely fail, putting your entire system at risk. It's annoying I know, but for the security of your entire computer, it's important not to be too much of a miser when it comes to choosing a PSU. The enthusiast series is one of the cheapest brands. (Don't go for the Corsair builder series, they're made with inferior parts.)
