Needs more AMD support for CPU.
About every part they gives are INTEL or NViDIA based, which isn't bad. but Needs AMD based too. some AMD cpu are cheaper than intels. so why not add that? example I prefer intel, but would prefer a FX CPU over a Pentium one. but thats me.
I’m afraid the choice of Intel or Nvidia is not brand preference but is due to the better pricing in the market at that particular price point.
In the case of AMD CPUs they are not actually cheaper or better for the money than Intel counterparts which perform better for gaming.
In the case of graphics cards, AMD tend to be the best up to the 970 and 980 in terms of bang for buck.
