Production based tasks, AMD. gaming, intel (barely). Also depends on the programs you'll be utilizing. If it's capable of being pulled through 4+ cores, and you will be running 3+ programs/tasks at a time, AMD is much stronger. as for the graphics card, if you can afford it, the 780's are amazing cards, roughly 500-560 depending on what you go with. If you're looking more at a budget, the 750 TI or 760 depending on your price range would be great choices. Since you said "close to high end", I'd strongly recommend going with the 760/770. If you do go with the amd proc, you can spend the extra cash you saved there on the better gfx card.
my 2 cents anyway.
