I have the chance to buy an i7 3770K for relatively cheap (well within an emergency fund I have for unexpected upgrade opportunities) but I'm not sure if it's worth it. Currently have an i5 3570K, and will soon be getting my hands on an GTX970 - besides this new GPU, I don't plan on upgrading anything else for at least a year (if not longer) - hence this little dilemma: stick it out with the i5 or get the i7 which would truly maximize the maturity potential of my current system (potentially pushing back the upgrade plan by maybe another year). I am genuinely open to suggestions on this since I am pretty much down to 50/50. Thanks!
