MacPro versus IMAC for FCPX

Trying to find out if a 2010 Apple Mac Pro "Six Core" 3.33 (2010/Westmere) with 24GB memory and two internal drives configured as Raid 0 will be able to play back a three to four camera multi clip in Full Quality without dropping frames or showing other signs of stress. I do know that a top of the line IMac with 8GB Sonnet thunderbolt, 2 GB video card, and 16GB memory will do this okay and even do it with a brown render line from color correction adjustments.
