Lol. Way to bend the truth. This is about CPU performance, not GPU performance. The test used is only to measure overhead and not overall GPU power. The scenario described in which the 290X performs equal is completely fictional and not even close to any real life gaming scenario. Of course any GPU will perform equal when running into a CPU bottleneck.
Both Mantle and DX12 will do close to nothing for actual gaming PCs because usually those already feature strong CPUs. 99% of current games run into a GPU bottleneck before ever reaching the CPU bottleneck.
Whoever owns a 290X or Titan X and frequently runs into CPU bottlenecks is doing something wrong with their lives.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
