Just a quick community question.
Upgrade from FX 8350 overclocked to 4.8Ghz, to an i7 4770k hopefully overclock to 4.5Ghz.

I know its not really worth the upgrade, since cost is $500-660 depending on hero/formula motherboard.

But overclocked my fx is running at around $250-300 a year for power consumption, best estimate correct if im wrong please.

Now, if im right, the i7 would be running around $150-200 a year for power consumption?
Again, please correct if im wrong.

So would, in theory, the move to an i7 be the right move? Since id be saving minimal $100 a year in energy savings, plus im guessing my chip ($200) and mobo ($150) could be sold on ebay for $250 bought new November 2013. So then in theory, upon energy savings and selling current, I would earn money spent on upgrade back in about 3 years? Which would probably be the lifespan of the pc setup before upgrading again. Thereby costing me nothing, and for a small performance gain?

when you factor for 7am to 11pm and only $0.15/unit then the sums work out at around $109 for a 125w processor, scale that by your OC. an intel would be 77w, this would be about $67/year, so roughly a $40/year saving.

Thanks for the quick reply, and new mobo will be either hero or formula. I want the formula but would be budget dependent. But will be either of those 2. Very much set on it, and have spend over 12 hours researching everything involving 87 boards.

As for cpu, from what ive found its 125w, under load around 180-200, but overclocked should be around 250w maybe higher. Now from what ive also found, that the stock runs about $200-250 a year. Im not stock so added about $50-100. It should be around there and im not going to get a wattage tester to plug in. My machine is turned on around 700am and off around 11pm.

Performance at what? Are you folding 24/7 or some such? That's the only way your system could possibly cost you that much per year.

This article is talking bronze vs plat power supplies, but that test system on the bronze costs about $365 a year (based on $0.12/KWh national US average) running the GPU at max load 24/7. Would be suprised if your CPU uses more than that since that's for entire system, even with your OC.

It wouldn't be a bad thing I guess but don't know what the ROI is.

Performance at what? ? when I said at the very end therby costing me nothing and for a small performance gain? That was meant as the small performance gain of the i7 vs fx. But don't think I was talking performance anywhere else. And as far as the annual price, that was taken off and figured off of several very similar sites in which all broke down and figured that annual power consumption of the stock amd fx 8350. Granted I know my gpu and othercomponents also have a huge factor, but I am just comparing cpu's. These sites state annual consumption for household around $150, and commercial $250. I'm leaning towards the middle of the two in my methodology. Since its on about 16 hours a day, and minimal of 4-6 hours of that is 75% cpu usage. Then factored in the overclock set me around 100w over stock at full load, since that's almost double stock, I took $200 (stock) added $100 (for the overclock). Yes I know this is no where near exact, and will more than likely be lower. But I did use this mentality on both amd and intel situations. So if I were to recalculate the amd and lower it, in theory the intel would also lower and almost equally. Thereby really keeping the main part of this the same, which is the difference in yearly power consumption costs. Which would be around $100.

And since my overclock is pretty significant, all power saving features (every one) are turned off. Which also factored into my decision to place my annual consumption between household and commercial.

Thank you! Not what I was hoping to hear, yet at same time glad to hear it. But best of all, great to know.
