Howdy Partner - AMD Joins forces for "Graphics Core Next"

I'm a little behind schedule in posting this, but AMD have partnered with Battlefield developers DICE and publishers EA for the upcoming release of Battlefield 4. This is mainly due to AMD's new technology, Mantle, which aims to be a low level API alternative to other solutions such as OpenGL or Direct3D (DirectX). Frostbite 3 (on which BF4 runs) has been confirmed as the first video game engine to support Mantle.

AMD claims that mantle will result in much better utilization of hardware, and thus an increase in performance. Given that it is proprietary software, only AMD cards will recieve the performance boost in games that support it. As such, large numbers of people have begun frothing at the mouth over AMD's new R9 290X graphics card, and understandably so. Will it be the Titan-Killer the fanboys hype it up to be? Or just a graphics card version of the false hope that was PileDriver?

Anywho, my question is this: have you ever bought any hardware in expectation of using it for a particular game? Let us know in the comments below :)
