hey fellas im running a tri 280 sli setup. I want to run 3 monitors so i need a 4th video board which sucks cause i dont want to add another to my open ended x4 slot but anyway. So question is if i gotta add another anyway, might as well make it a dedicated physx card too. It must be single slot, and hopefully not draw crazy power(my poor corsair hx1000 cant take much more im sure). Thanks for any guidance you can give.
