I have been looking around the web for a good answer to this, but I can't find one. I know the more you have, the better. But how much better? Like will an 8mb cache be a lot better than a 6mb cache? Or a 4mb cache?

How effective cache is depends on how the cache is organized, how the CPU manages it and how well the code and data are structured to make the best use of them.

For some workloads where the CPU streams data from RAM to GPU with some on-the-fly processing as is often the case in games, cache has little influence.
