BenchmarkReviews.com: PowerColor's a familiar name to the AMD Radeon community. If they don't offer the widest variety of variations on AMD's reference designs, I don't know who does! They have no fewer than eight different versions of AMD's Radeon HD6850 card, ranging from factory-overclocked "PCS+" variants to a single-slot-cooler version to the one Benchmark Reviews is looking at today: the passively-cooled PowerColor SCS3 HD6850 1GB GDDR5. This card uses a massive fan-less heat sink to offer the performance of an HD6850 without any noise at all, and is certainly one of the highest-performing graphics cards I've ever seen with a passive cooler. Will this really work? How far will it overclock? Let's take a look.
