the board will take 32gb but I will see.
I have 32GB in my gaming/video editing PC, and it's total overkill right now. The only real benefit is that the second time I load a game in the same session it's at least twice as fast because all the files are cached in RAM.
I only loaded it up to the max because RAM was cheap at the time.
My i7 is also total overkill, as I rarely see games use more than 30% of it. Only video and 3D graphics rendering can really get close to maxing it out.
