I wonder how the GPU performances will be affected when AMD releases the Mantle API for the PC platforms? Rumour has it that Mantle will make the AMD GPUs beat the crap out of the nVidia GPUs in terms of gaming performance and will force nVidia to dramatically reduce the prices of their GeForce cards as soon as in this November.
Mantle needs each game to be coded for it. So far, zero games support Mantle. BF4 will eventually support Mantle, but that's just one game. Since Mantle is PC-only, it's extra effort for the game developers, so I'm not convinced it will gain much traction.
In any case, it won't really be relevant within the next few months. The rumored Nvidia price drop has more to do with the simple price/performance ratio AMD offers on their products, regardless of Mantle.
