That's actually a really good list. I usually use a 1000W power supply, but that's my preference. I'd say go with an 800 rather than a 600 though.

I think it'll be fine, you've got the necessary things I'd use [been building for years], like an SSD, 16-32GB of memory (which will definitely make things better), and a good GHz quad-core.

My preferences are Intel and nVidia, so personally I'd recommend swapping the Sapphire for an equivalient nVidia card, but that's me. PNY offers nVidia cards (usually I find them on newegg.com but anywhere will do) that are cheaper and still high quality. Lots of companies sell nVidia cards but PNY is the highest quality for the cost.

One other thing you may want to look into as well is the CAS latency of the memory sticks (often written as 9-9-9 or 9-9-9-18] the lower the better, though these days you can't seem to get lower than a 7-7-7.

Microsoft - Windows 10 Pro OEM 64-bit: This is what I'm using. I've gotten pretty used to it, but there are weird moments when it will freeze for 2+ seconds, or I have to click outside of the program I'm using, then back in to continue what I'm doing. So far Microsoft support forums have been very poor in treating my problems with this operating system. Unfortunately, I wouldn't recommend going any older, since support will eventually end for older operating systems.

i7 Core: Great! I use an i5 and it seems to do everything I need it to.

I hear Liquid coolers are great, but they are also probably more than you need. I use "Cooler Master - Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler" at $24. I can run League of Legends on all high graphics, Flash CS6, and CSP all at the same time without problems.

Motherboard: I run a Asus - Z170-DELUXE ATX LGA1151 Motherboard, so I don't have experience with the type you have. As a heads up, it probably comes with an installation CD that has a bunch of drivers. I don't recommend installing them! Use the Windows recommended drivers instead. The Asus ones (or at least the USB drivers) weren't compatible with the Windows 10 drivers and kept sending me into a blue screen loop, where I'd have to clean install the OS.

Storage: Your hard drive is intensely overkill, I feel. xD A 1TB SSD might do the job just as well? BUT if what you have picked out is affordable enough, it probably won't hurt to have all the extra space, either.

That's all I can kind of comment on as far as knowledge. I know my Monitor costs a bit more (though I feel like it's probably a less important part of the build), but there's a few of your pieces I can't comment price wise.
This is my build, if you want some sort of comparison: https://pcpartpicker.com/list/FHwW6X

I also highly recommend Newegg and Jet for buying your items. Amazon is also great if you have Prime, but they charge you tax when you check out, and it adds up quickly.

The only two things I'd be wary of are the liquid cooler and the power supply, but only in the general of terms: liquid coolers have a higher chance of breaking down if you're not careful, and in general if you can afford it having a stronger power supply is better.

I'd def go for a bigger power supply, thankfully they're not toooo much more expensive.

As well as maybe toss in a 500gb SSD for windows on its own. That way you have no hiccups with running windows while also using bigger canvas's on photoshop and everything else.

Windows would hiccup for me sometimes. One day I had to nab an SSD, grabbed a Samsung 800 500gb and now I have no issues with canvas sizes.

The power supply upgrade would be amazing because if you EVER want to upgrade your graphics card, then you're set on that.

If you POSSIBLY can splurge, I'd def upgrade the graphics card, but at least with the power supply and SSD, you'd be set for a good while.
: )

Also, from my experience from coolers, the higher you pay, the better you get. They're great, but very finicky to put into place. I have had experience with the one you're picking out, and it works and does its job, but when I gave it to my cousin, he has had some issues with dust collection on it.

Depending on your area and how much dust you have around, I think that would be your deciding factor. : O

Thank you for this! I was actually gonna show my updated build as well as things i wanted to get for my streaming/gaming setup. :]
