The SOC has a nice overclock that places its performance very close to the GTX 570. The MSI 570 Twin Frozr has a relatively small overclock. So at stock speeds, both are similar in performance, with the 570 running a little faster. Of course, if you plan to overclock, the MSI 570 Twin Frozr III has more headroom than the 560 SOC, so it has much more high-end potential. Either will meet all your gaming needs and both have very quiet and cool heatsinks.
