Sapphire are probably best known for their amazing Vapor-X cooling solution. Probably the best graphics cooler available on an out-the-box GPU. They have got three different models of the HD5770 available. The HD5770 we're looking at today that uses the original reference cooler, the HD5770 New Edition that uses the modern ATI Reference cooler that expels air into the case rather than out the back, and the HD5770 Vapor-X. Because we're looking at value we didn't want to look at a card that comes with a premium cooler, nor one that is already a little overclocked. We want to start at the absolute bargain basement HD5770 and see exactly how much performance can be tempted out of its silicon.
