A friend of mine needs a new computer for graphic design only. He uses After effects, maya, photoshop, bridge and indesign if that says anything 
I was mainly wondering about cpu, gpu and maybe amount of ram needed. Budget is about £1000-£1500 and he only needs the computer with case and OS.
Would i7 2600k be enough or something like i7-3820 much better? I was thinking about 16GB ram and something like GTX 560 as gpu. Any of these programs favour Nvidia over AMD?
All comments appreciated since I have more knowledge about gaming computers
