That's a good build for gaming, nice choice of components. i5-4460 and GTX970 is a good pair, even any i5 can handle GTX970 well.
Any CPU can
"handle" any GPU well if the workload is well suited to the balance of compute vs render performance. Your statement is based on a fundamentally flawed premise. I would like to see this mysticism about the CPU/GPU relationship die, but unfortunately, it keeps being recycled and repeated like a bad mutating virus.
The i5 is a good gaming CPU regardless of which GPU it is paired with.
The GTX970 can be used to accomplish high visual quality goals, or high FPS goals, or a balance of the 2. When used as part of a system with high FPS goals, it should be paired with a powerful CPU. When used as part of a system with high visual quality goals (less FPS), it can be paired with weaker CPUs without ill effect.
Stating that a particular CPU "handles" a GPU well is highly misleading, as it implies that the compute workload is higher with more powerful GPUs, and lower with less powerful GPUs. This only holds true if we assume all GPUs up for consideration are forced to run games at the same detail settings (like a GPU benchmark). In the real world, we can inversely adjust visual quality and FPS with any GPU, thus, the compute workload can be adjusted up or down depending on FPS vs visual quality goals on any GPU.
Example:
Maintaining 60FPS in a compute intensive game will have about the same CPU performance requirements whether on a 720P monitor with a GTX750, or at 1440P on a GTX980. The i5 is a good CPU choice for maintaining high FPS in compute intensive games regardless of the GPU selected, as both the $100 and $500 GPUs can play games at 60FPS, the difference is visual quality while doing so.
Said another way:
Match the CPU to the compute workload generated by the FPS goals in the games you want to play.
Match the GPU to the render workload generated by the visual quality settings and FPS goals in the games you want to play.
Any attempt to match the CPU to the GPU, or the GPU to the CPU, rather than matching each to the workload, is just from-the-hip conjecture.
