Ok so which one? The 7860k or the 7850k? I also remember reading somewhere that only r7 graphics cards would work with the apu.
Not at all. You can use any video card you want with them. They have "R7" graphics built on to the APU. There is a thing called dual graphics which is a hybrid crossfire between the IGP on the APU and a dedicated GPU but I would highly recommend NOT wasting your money on it. It is always better to get a single more powerful GPU than two in a SLI or Crossfire especially if it is a hybrid crossfire.. What are you planning on using this system for? Oh and the only difference is the clock speed between those two APU's you listed. Both are unlocked so you can overclock the cheaper one to the same clock speed as the more expensive one.
