Building First Computer for Content Creation - Feedback Welcome

Hello Razer Community,

Hoping to get some feedback from some folks who may be willing to help and share their input on something. Specifically, I'm looking to upgrade my current system, and will be using my new NZXT H510 Compact Mid-Tower ATX Case I received from a recent giveaway! I've been planning this for a while now, and have had some input from other folks throughout. I'm just about ready to pull the proverbial trigger, so to speak, but thought I'd get some input from you folks!

First and foremost, this will be used for content creation (gaming, streaming, videos, etc). I'm looking to essentially upgrade my current system, which is an HP Pavilion 500-189. Recently, I received an NZXT H510 Mid-Tower ATX Case free (minus duties) from a giveaway, and so am looking to use that. One thing that seems to come up regularly from others is the case. Many cite the fact it has poor airflow, and recommend I go for a different case - frankly, my current system, when the side is on, has very little airflow, so I'd consider this one to be a considerable upgrade, lol! That said, suffice to say, I'm not looking for a different case. Aside from the case, I do want to stick with AMD - that's another thing that kind of comes up regularly, as a lot of folks will recommend Intel. I'll admit, I've never tried Intel, so don't have anything against them persay - I would just like my first build to essentially be an upgrade of my current system, which is completely AMD. As for anything else, I do want an ATX motherboard that will fully utilize the case; I also wish to make sure I fully utilize the case itself. I may potentially be a bit picky here, but, the essential "must haves" (technically wants, I suppose) include:

AMD
Compatible with and Fully Utilizes NZXT H510 Mid-Tower ATX
ATX Motherboard with WiFi and Fully Able to Utilize the Case
Compatible with my Current BenQ RL2455HM Monitor
Sticking with Traditional Black/Green Razer Theme Colours*
RGB is Optional**
Budget is $1,500-2,000 (CAD)

*Not an absolute must - gold, navy, silver, et cetera would be okay, but hoping to avoid any "eye-popping" colours that really stand out (e.g. cyan, pink, red, white, etc); though, green is my favourite colour, so would consider it a huge bonus if the whole black/green colour scheme could be maintained as best it can!
**As I'm not likely to fully utilize it (I'd honestly probably only have it set to green), it might be a little wasteful to get.

Thus far, this is probably the one I'd consider best overall that I've had suggested: https://ca.pcpartpicker.com/list/4xrntn. One that is similar, with some alterations: https://ca.pcpartpicker.com/list/sDg2mr. Another (not quite as complete a list, and CPU isn't AMD) that was also recently recommended and seems okay: https://ca.pcpartpicker.com/list/MYzjZw. One thing I immediately noticed with the first is the compatibility note that says "The MSI MAG X570S TOMAHAWK MAX WIFI ATX AM4 Motherboard has an additional 4-pin ATX power connector but the Thermaltake Toughpower GF1 PE 650 W 80+ Gold Certified Fully Modular ATX Power Supply does not. This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it." As I understand, it's not 100% necessary, but am wondering if there's a similar power supply that has this connector (perhaps one of the power supplies in the other lists have it, but not sure). Another thing I noticed is the core thing with the central processing unit; from what I understand, the higher count ones are more-so recommended if you're doing something like 3D game design, and there's some standard of core count when it comes to gaming (not sure if it's 8, 10, or 12) - is that actually something I should consider bumping up, and, if so, would I be able to get some recommendations? As I understand, the motherboard is kind of like the backbone for the system, so I want to ensure I have a solid one, so to speak; the one in the first list seems reasonably priced, but wonder how it compares to the others; I realize the third appears to be for Intel, so wonder if there's one similar to it, and around the same price, that would be compatible for AMD - if so, how would that one compare to the first? Aside from that, I figure the power supply and graphics are also fairly important, and things like memory are secondary.

I'm a believer in the old adage "you get what ya pay for," but I realize cheap doesn't always necessarily mean something's terrible - likewise, more expensive doesn't always mean better. I also don't necessarily mind if it's not the most recent "generation" hardware. During some quick research, I searched for "what company is known for good motherboards for gaming" and "best name brand motherboard for gaming" - suffice to say, both came back with different results, so it's certainly confusing to say the least. Though, one did kind of stand out, as I had read an article - this one here: https://www.techradar.com/news/computing-components/motherboards/best-motherboard-14-reviewed-and-rated-904229 - that suggested it as being "best high performance for AMD": the Gigabyte X570S Aorus Master. That said, cheapest one is like $450, but not in stock, while the only one in stock is like $750 - honestly, just seems a little high (even the cheapest one that's out of stock), in my opinion.

On that note, I am looking/shopping around to see who can give me the best prices on this. As I understand, some things are a little overpriced these days (for instance, I understand the GPU is a bit overpriced in the first one by about $200 or more), so have made some inquiries to different places to see what can be done to knock the price down a bit. In the meantime, hoping someone might be willing to offer their insight! :)

Sincerely,

DawsonJr
