Though are builds are slightly different.. they are close enough for us to benchmark them against each other. One thing I can confirm as of now.. while tessellation is on. His 5970 ,sadly, doesn't stand a chance against my setup with 1 480 (other 480 on physX). So we made the agreement to, when possible, not run tessellation during our benchmarks.
