And has very little to do with CPU speed. There are some games where CPU speed is important but there's a large subset (I'd be willing to bet 95%) of AAA games where only GPU speed is important and they run just fine on low end CPUs.

- corillian 13y agoThe whole point of D3D12 and Mantle is to decrease driver overhead, improve multi-threading support, and increase the number of per-frame draw calls that can be made. Those are all CPU performance improvements so I think it's safe to say that CPU speed is quite important or else AMD and Microsoft wouldn't be going through the trouble.

There is an reason why review sites use games for CPU benchmarks. As you can see some games are indeed GPU bound. But vast majority is actually bit of both, e.g some section of it is purely CPU bound while another is purely GPU bound. So improving either component will increase FPS.
