OK, we're through playing nice with these new ATI 5xxx video cards. The corporate logo for XFX says: "play hard.", so Benchmark reviews is going to take that motto to heart and show what this cards can really do. Almost every single competing card runs at higher than reference clock rates, and they all come that way from the factory. Every single card I compared the HD5770 to, when we reviewed the reference design from ATI, was factory overclocked. That's just the way it is with video cards built on mature GPU technology. Well, every ATI 5xxx card can easily be overclocked using the standard driver package from ATI, Catalyst Control Center, since it includes ATI Overdrive. So let's do it, let's compare apples to apples, and as a bonus, I'll throw in some CrossfireX results, too.
