So I'm building my first custom gaming PC, and I'm going with the Asus Sabertooth Z87 motherboard and an i7-4770K CPU. My question is this: What would be more efficient, more affordable, easier to assemble, and overall just the better choice; a good heat sink fan, or a water cooling system for the CPU? Hope to hear a bit from each biased side so I can hear pro's and con's of each. Thanks!
