Under $2000 Gaming PC Recommendations Assistance

Well I would plan on overclocking (I know it improves performance and in the Intel i7 4770K it will double the usable threads; otherwise I don't entirely know what it is, or how to actually set it up). I just need to figure out its whole practicality in the PC, but I hear it will aid in video editing and further future-proofing it. Also it's Australian Dollars, but they are close enough; and the budget for the Keyboard, Mouse, and Monitor is not really defined (goes for the PC itself as well, still aiming at under $2000), but I'd like to try and get the best bang for buck, whilst also having a decent performance. Hopefully noise isn't a big problem if I have liquid cooling, aiming for this build to last a few years before the next upgrade. Not sure if I should move up to the GTX 780, or stay down with the 770. Kinda want to know the whole deal with overclocking, because it could very well save me a hundred dollars, but I hear that it may assist in futureproofing the machine.

Basically trying to get the best bang for buck, between $1500 and $2000, with a PC that will comfortably run high end games, and can manage video editing. I also already own a mouse, but not a very good one.

Hey I like what you are saying here, and I like even more that you've managed to find it all (including peripherals) under the $2000 mark. Whilst I really like what you've pieced together, might I ask some questions as to gain insight on the matter.
Firstly, as I have heard intel will be releasing their next generation processing cores soon, would it be wisest to wait until that release, and pick up the i7 4770K since the price will have dropped, or by that time would the next generation i5 core be a more worthy cause. Because if I can wait it out and grab the i7 4770K at a low price, it might just be the best option. Also further on the CPU; is hyper-threading going to be something that I should allow for in the next 24 months to come, or is it really not that necessary in today's games. Since I believe that the i5 4970K is still a great core, will it still be able to (even if not up to the excelled performance of the i7 core) run some video editing programs (this is not long extended movies or anything professional like that, just will it be able to handle it)?

Secondly, since you believe that sticking with the H110i is still going to be a worthy action, would you then recommend superclocking the PC, to gain as much performance out of it as I can? Superclocking is really out of my understanding at the moment and I must wonder how it all is set up, and what overall boost it will give. I still think it must be good though; and the CPU cooler should be able to keep the CPU running fine.

Is the Motherboard much of a difference to the Z87 Sabertooth? I see the Sabertooth as thermal protected, dust protected, well built. But the only difference I can ultimately see between the Maximus VII Hero that you recommended, and the Z87 Sabertooth is a "TUF Protection" over the board. If the Maximus VII Hero is the way to go, then I'll probably head that way.

I hear a lot of back and forth arguments between whether I should go 16GB Ram or 8GB Ram. I know that many smaller games will run at 4GB fine, and so many high end games will run 8GB fine as well; but with there being video editing and lots of programs and the sorts, is 16GB the way to go, or really just something I can add later on at the next upgrade, as gaming will only require the 8GB, and the minimal video editing should be able to deal with 8GB. From what I know, I think 8GB will be fine for me for the first while, and it's very easy to add more later on, but just wondering as there is a hot topic on that matter.

Storage I can't really complain about, as long as I can keep my OS on the SSD and be able to boot up quickly and run some games quickly through it, and then be able to store everything else on a larger Hard Drive then I am all good with that; so thanks

Video Card I know the GTX 770 to be good for current day games, so I will take your word for it.

The case is too one that I thought to be well built and of good features, just wondering if air-flow will be alright for it, as I know that the Corsair Carbide Cube Case has an excellent airflow, but the Vengeance is quite well made and built for the job. But will the vengeance fit everything? It looks like it will, but I'd like to make sure it can hold the Water Cooling unit, and the graphics card. Just aside from the case, will I be able to control fan speed through the motherboard or even the case, if not then I probably won't even notice it in the first place. Just wondering on that topic.

With the Power Supply, since these are one of the first to break in a PC (along with the motherboard), should I spend the extra $50 and get a gold rated PSU or will the Bronze Corsair model be fine? This goes also for the motherboard in terms of its durability.

Optical drive, not that it matter too much, but should I go Blu Ray, or just leave it up to the online movies and TV Shows?

Operating system sounds fine, don't really know what the difference between Windoes 8.1 64 bit, or the Windows 8.1 64 bit PRO. Doubt there's a major difference, but if it will vastly improve the performance then I'll ask for its worth.

Monitor I am glad you managed to fit it under the $2000 mark, it is the one purchase I was a little bit worried about, and if you think it will hold its own as a good monitor that will work fine and not ghost too badly, then thanks.

Keyboard and Mouse are both items I can get for free (in essence). Really what I have to ask there, in what you believe is best to go for, don't worry about the budget there but try to be reasonable. Death Adder sounds great will go for it, and Keyboard could still use the guidance.

I think you've done a good job, and really I am not going to be using this computer "HardCore" or excessively overpowered. As long as it can run games comfortably, and can actually run a video editing program without crashing, then I am all good with it. I have a little MacBook Air that was a gift to me, and I'll be running that as like my second screen for Skype calls whilst gaming, or for Facebook or just stuff in general, but it has been able to run Video Editing programs like Final Cut Pro, not that it ran it efficiently, but it ran it. So as long as it can run Premier Pro better than a Macbook Air, then I will be grateful.

But thanks a tonne for this, if I could just get the round off reasoning for your ideas, then that'd be great Really want to see this computer be able to beat a computer (in performance) that costs the same amount in price.

Hey, thanks a tonne. From what you've said it would appear as though it will all come together well. The recommendations have been enormously useful and I will definitely use your ideas for parts. Thanks a lot
