Anon... these are old processors so you should be looking at craigslist or ebay. The 4790K might be overpriced anyway as it's one of the final upgrades for that generation.

>what is overclocking
Probably for the best if you just buy the bundle or something. You're also wasting money if you get the Z-chipset or K-processors since you're not comfortable with overclocking.

You should still get the GPU first.
