Using GTX 750Ti for iRay

Well, as I'm still waiting for a new power supply, I have wondering, now I have a new GPU (replacing the 8400GS), will it support iRay at this point? I have a GeForce GTX 750Ti GDDR5 w/2GB at this point, and so I have a intel i3 3.30Ghz quad core, 4GB of ram. I tried iRay once, but I think that because my old card is not enough to run it, I tried running with CPU, screwed it, switching to Reality/LuxRender. But now with that out of the way, I'm wondering, that if it works with that new card (as I think it should). I won't use TO MUCH of the shaders, really. But if it works, if there's a way to have a iRay render preset to ease the render on my new GPU.

    2GB of GPU RAM, and 4GB os system RAM< are going to be fairly limiting in the complexity of what you can render I fear, but yes the 750 should be usable by Iray to speed rendering of scenes that fit in its RAM. As for shaders, you may be better (where possible) using non-texture shaders to reduce the RAM consumption.

    Even if I upgrade the RAM to 8?

    System RAM will help with scene management and CPU rendering, but it won't let you do more with GPU rendering.

    My experience is IRay running on a CPU uses every bit of system RAM it can get it's paws on.  I would upgrade to 8GB at least.  I'm planning to go to 32 or maybe 64 in my next system.  I run IRay renders on my GT 750 M all the time without problems, though IRay drops to CPU render if the scene has more than one model in it.
