4790 vs 4820k?

The i7 4790 is the newest, and fastest, quad-core Intel has to offer.

The CPU is both very similar in price. What is better for 5 boxing? How significant is the difference between a bigger CPU memory cache and supporting a better memory system.

I doubt a bigger cache would give a noticeable difference when playing a game, and how much memory you need is only something you can answer yourself. Do you need more than 32GB of RAM? Do you expect to be running more than two GPUs (or other devices which take up PCIe slots)?
