Using a GPU as a dedicated PhysX card?

So I unfortunately had to sell my previous gaming PC to pay some bills. :( But hopefully with the tax return season, I'll be able to buy another one! But I'm looking at one from a local buyer, and it currently has an R9 290 in it. I would want to upgrade to a 970, but it got me thinking, how beneficial is using another card as a dedicated PhysX card? Obviously I couldn't use the R9 as one, as it's an AMD, but if it was an Nvidia card is it really worth it? Would it better to keep the 290, and rather than upgrade to a 970, buy a cheaper card to use as a dedicated PhysX card? If so, what card do you think would be the best option? The main game that I'm going to be building this game towards will be Witcher 3, but any of the high end AAA games that will be coming out soon, I'll be getting for PC as well. (Dying Light, AC Unity, maybe FC4, etc etc). Any help would be very appreciated! :)

Technically PhysX is only Nvidia.... so if you want to dedicate a card for it you'd have to have 2 Nvidia cards... This has proven to boost performance slightly at worst cases and decently in higher intensity games. It really just depends on the other model card you plan to pick up (speeds, memory, etc.), not that a 970 won't be good enough at 1080p by itself...

So you can only do that if both cards are Nvidia? Like is the PhysX only enabled if your primary card is Nvidia? Or could I keep the 290 and use an Nvidia card for the PhysX?
