The 5950X hasn't even been released or at the least reviewed yet. It's hard to make any conclusion as of yet but if you are in a major game development company then a 3970X will definitely be your obvious choice. Though if you're a small game developer and want an overall cheaper build on a newer matured architecture then the 5950X is the way to go. Given AMD knows people buy these chips to game on they most likely optimized the architecture to run faster with single core and with less latency/higher efficiency. An ideal choice for small game development.
