Right now, PCPP has this build rated at 484W. I had considered buying a PSU able to go crossfire just for the sake of a little future proofing just in case black friday or new years saw a nice sale on GPUs. Unfortunately, going CF on that card knocks the power all the way up to 734W meaning that, if I were to buy a PSU big enough to go CF now, I would be looking at probably 800W min, which is certainly a big overkill without the second card. A couple cards I see as of now,

XFX PRO650W Core Edition 80+ Bronze: $69.74 www.amazon.com/XFX-PRO650W-Bronze-Energy-Certified/dp/B0045L5LGI/ref=sr_1_20?s=pc&ie=UTF8&qid=1402061635&sr=1-20

XFX PRO750W Core Edition 80+ Bronze: $76.24 http://www.amazon.com/XFX-PRO750W-Bronze-Energy-Certified/dp/B0045L4BJ6/ref=sr_1_38?s=pc&ie=UTF8&qid=1402061669&sr=1-38

EVGA SuperNOVA NEX 650 G 80 PLUS GOLD: $59.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16817438026&nm_mc=EMC-IGNEFL060614&cm_mmc=EMC-IGNEFL060614-_-EMC-060614-Index-_-PowerSupplies-_-17438026-L09A

open to other suggestions.

List of 800-1000W PSUs on PCPP http://pcpartpicker.com/parts/power-supply/#W=800,1000&sort=a9&e=4,3,2 but that really does seem like overkill for just the potential of CF.

If you are planning on doing CF at some point, keep in mind that there is no such thing as really going overkill on your PSU. Sure they are most efficient somewhere near 60% of their rated capacity, give or take 10 or 15% depending on teh design, but the difference is minimal.

If you truly are going to do CF there is no point in not buying to prepare for later.

Also, keep in mind that for a gaming rig you would probably be far better off with a 4670k, or even the new unlocked Pentium over the 8320. The only reason you would choose the 8320 is generally if you were making a work horse rig that does something like x264 encoding all day, but you also happen to want to play some games on it. If you went that route you can take about 50w off of your usage estimates too, which could make the PSU choice easier.

Also, if you went with an NVidia card you could use shadowplay for any game recording or streaming so your processor doesn't have that work to do which would make your game run smoother during those situation, and most of the NVidia cards use less power than their AMD equivalent, which would also ease up the requirement on the PSU.

As an added note, don't bother with PSU calculators, they always way over estimate your actual usage. For example over on the Anandtech test bench they measured their whole system usage with a 280x and CF280x setup at 360 watts and 671 watts respectively. Keep in mind that this is measured from the wall side so the PSU is delivering less, so if it was a 90% efficient power supply they used that means the PSU was delivering about 325 watts and 604 watts respectively, not 484 and 734 as your estimator was showing.

also, on an unrelated note, I dont plan to do alot of overclocking at least not right away. How are the 4570k stock fans? good enough if you arent OCing? same question for the 8320. If they are fine on the intel, then I could bring that price closer to the AMD anyway and just grab the fan some other time.

The stock fans are designed to run the processor how it comes out of the box. It won't be super quiet, it won't be super cool, but it will work just fine.

This is completely ridiculous. Think of the millions of machines that are running every day with stock coolers... Aftermarket is great for low noise, or low temperatures, or overclocking. Stick processors will run fine for years on the stock cooler.

Mostly that's from lack of air flow in custom cases, or from overclocking or adjusting voltages. The stock fan will cool a stock processor just fine. I also didn't tell you that you are stupid, of course you lied before and are just continuing your trend. I guess everyone should just trust you that Intel has never sold a processor that ever didn't need it's cooler replaced immediately. Nope, the millions and millions of processors over the years they've made not one survived with the stock cooler on it . . . you see how silly that sounds? That's how silly your recommendation that you always have to use an aftermarket cooler sounds too.

Well, after doing some thinking and research, I realized a part of my decision making probelm was that I didnt have a solid budget put in place. SO, if I want a full system monitor and everything (which I should be getting from a friend) for $750, I need to get the 8320 and just went with a 650W Gold EVGA PSU on sale today.

Other research has said that the reason some people experience fps drops on the fx chips is due to automatic throttling done by the chip once it reaches a certain temp (62C?). Thus, Cooler Master Hyper 212 EVO and Arctic Cooling MX4 is on the way as well.
