Sapphire Radeon HD 7950 3GB Vapor-X

Overclockers Club put the Sapphire Radeon HD 7950 3GB Vapor-X through a battery of benchmarks, crunched the numbers and jotted the whole experience down on paper. Well, not really paper...but you know what I mean. Here's a quote from the review: Overclocking the Sapphire HD 7950 3 GB Vapor-X was an interesting endeavor. Using the included Sapphire TriXX software was quite easy and intuitive, so the software really wasn't an issue at all. Using Unigine Heaven 3.0 looping for 30 minutes at a time, I slowly brought up the core clocks; after settling on a maximum core clock, I did the same thing with the memory clocks (while leaving the core clock at the maximum stable value). Usually, this process goes quite smoothly, but for some reason, this card was a bit more picky than most and took me a lot longer to settle in on stable values.
