Which Nvidia card should I get to run hybrid physx with two MSI R9 290 Gaming's in crossfire? I have a GTX 680 Lightning, but trying to sell it and get a cheaper Nvidia card for hybrid physx, should I sell it (bought for $500 3 weeks ago, selling for $375)?

My motherboard is an MSI Z77 Bigbang Mpower, case is a Corsair 550D, don't know if I can fit two R9 290 Gaming's and a GTX 680 Lightning into it. Would there be air flow problems? I used to have two GTX 680 Lightning running in SLI and the top card was 15-20c hotter than the bottom one. Also there is a PCI-E sound card above the top one.

My CPU is a i7 3770K, PSU is a Corsair 760i, would there be enough power supply, would the CPU get bottleneck?

Does Physx work with Mantle, or does it only work with DirectX?

My old setup:

You could use something like a GTX 650 for PhysX, and it would be fine

GTX 650 would be my recommendation.

DirectX, in theory, would work with Mantle, but since its Nvidia technology you likely won't see it on any Mantle-supporting games.

Don't forget that you are going to have to jump through some hoops to get PhysX working when an AMD card is in the same system.

Yes it will be a trick to get it done, but its been done before

I aim for Star Citizen, which will have both Mantle and Physx implemented. But it seems only the old Physx (older than 3.0) can go hybrid, Star Citizen is 1 year away from release date, I'm pretty sure they will use the latest technologies on the game. Or maybe I should wait for the up coming Nvidia cards, if there is any? Something which has good processing power, a lot of VRAM to handle 5760x1080 and Ultra HD, with a reasonable price (about $1000). The Titan is about $1000 too, with lots of VRAM, but its processing power seems not so good. I would like to do Ultra HD at 50-60fps, with Physx enabled.

well maybe top end maxwell will be able to do that which expected to come out at the end late this year (or early next year). and maybe you might not need mantle either to get more performance from the game.

There's a Titan "Black" on the way and a GTX 790 dual GPU card as well.
