So i'm on the market for a high-end gaming/multi machine. More gaming. I'm looking at the i5-2500k/i7-2600k/i7-2700k vs i5-4670k vs the best AMD offering. I wanted to stick to Intel, but I can go either way. Budget is no set price. Just want a good high-end bang for buck card. I read the newer cards don't compete with the 2500k or 2600k on performance or multi threaded task.
