Yea they work fine, Intel CPUs are just faster, and Nvidia GPUs play a little smoother. Nvidia plays smooth using a AMD cpu also. AMD GPUs have a little problem with microstutter and crossfire. but work fine with Intel cpus.
Intel/Nvidia tend to be more expensive then a rig with the same performance if it were all AMD.
AMD makes ATI, so of course they won't have issues with each other. Intel, however, does not make Nvidia. No problems at all with whatever setup you choose/chose, just personal preference.
