Your build isn't as good as can be for the money because you choose to go with too much RAM and for your purposes, and overpriced motherboard. The PSU I choose is similarly priced, has a greater capacity, and just plain better. Its newer, has better quality parts, and can even OC (not your CPU with this build, but your GPU for sure). 16 GB of RAM probably never would have been utilized, so why get that much? My motherboard is better because it is cheaper, because it doesn't include features you would never use. As a result of the RAM cut and different motherboard, I could include a better GPU (actually, a GPU at all). Any performance build requires a GPU. When using IGP, the RAM it used is the slower system memory, and is usually capped at using only 2 GB of it. The GPU sports 4 GB of far faster VRAM, which loads textures and pre-renders frames better.
