no high end gamer cares about perf/watt. Every high end gamer will have a decent psu and case and all gamers care about is perf/dollar, or even more importantly is perf/pci lane. They will always stick whatever is faster in their pci lane and they couldnt care less if it runs hot or not. Its the fps on the screen they care about and Amd needs to start pushing more out of their chips especially if they have the headroom for it. The best they can do within 300w is what they need to do and not this perf/watt bull. That is only relevant for mainstream players and htpc users.
