asus tuf then

It depends on your budget.
 
I'd rather get a MSI B450 Gaming plus instead of MSI Tomohawk if it means I'd be able to buy 16 GB of memory instead of 8 GB.
Also, maybe consider 3000 Mhz memory instead of 3200 Mhz if that gets you in the budget for 16 GB.
The performance increase from going to 3200 from 3000 is not really that huge or noticeable... if it's something like 10$ difference or more, save the 10$.
 
What's the price of the RX 590 where you live?  Maybe you could get a good deal on a Vega 56 around the price of a RX 590

That entirely depends on the games... In general the GPUs trade blows across the board.
 
Specific software use is important at this point.

1660 for sure

1660 wins in gaming, what software for editing are you considering?

Get the lowest timings possible on 3200 if you ask me

The B450 Tomahawk Max should be the same price as a normal Tomahawk

Then get the regular Tomahawk or a Strix

Tomahawk Max or an X570 TuF

For best BIOS, get Asus. For more features (usb ports etc) - probably MSI. I'm trying to not using Gigabyte based on my bad personal experiences.

would look into MSI

Then you want a case that supports ATX motherboards. You can get midtowers or full towers. Full towers offer the best compatibility, but are fairly large.

Yes. Though check for a Sapphire Pulse/Nitro or Asus Strix as well. Those are even better

Personally I would go with the Gigabyte card. The MSI cooler doesn't look particularly effective, and if what 5x5 said is true, definitely avoid it.

The Armour cooler is awful. Avoid it like the plague.

None Get a vega 56 pulse used or new

Nice

All this above with the following caveat:
 
If you do go ryzen 3600, grab a board like F'n awesome sauce said above:  not an x570, as the premium price is too high on those.  A last generation board (B450), but grab one that has been pre-updated so you can drop the 3600 in rather than having to deal with instant flash or ordering a boot kit and waiting for it. (Tomahawk B450 MAX is an example, the MAX version is already compatible with ryzen 3000 series and is very reasonable price)
 
Just sayin, if it was my first PC build, I would not want to deal with multiple bios updates (some of those boards you have to update multiple times) and I might not even have known much about what a BIOS is, how to update, and wouldnt want to wait for a boot kit in the mail to get rolling.  Its his first build, make it easy on him.  

A few thoughts:
 
In terms of your budget and it being your first build, a ryzen 3600 would be the go to right now.  Not only possibly the best value CPU on the market right now, with a cooler included that will do great, but also there is no need to mess with any overclocking, just hook it up, mount the cooler and it will regulate itself based on your setup (power it gets from motherboard balanced against cooling).  That is the single best thing you can do for your build IMO.  I would take that over either of those intel chips.
 
I was powering a prior system (ryzen 2600 + 1660ti) on a 450w SFX power supply without any noticeable performance drops.  550 should be plenty to power anything in this price range.
 
Have fun!!!  Building a PC is fun, feels rewarding, and there is no better value/dollar way to get a system.  If you go to a store and buy a pre-built mac or PC, or order from a system integrator, you will be spending 15-30% more than what you are getting, and building a PC yourself is hand down the best value out there!  Also it is quite fun to tinker with.
 
Enjoy and GL!
 
 
 
 

yes... and no. Ryzen overclocks due to how the chiplets work there is a few settings to work with but its usually best to let the system handle most of it.
 
of note to improve performance Ryzen likes the fastest ememory possible so def don't skimp there.

warning there is a B450 will need a bios update to accept the R5 3600 this means usually you need an older amd chip to preform the bios update to accept the new chip. 
 
alternatively you can get a x570 board which will already be able to out of the box take a R5 3600

This is a teensy bit overbudget, so you could get 2x4GB instead of 2x8 if you want to spend less, or go for an RX 580 instead since it's still quite good.

650 watts is honestly overkill for most builds. rarely do they even need anything over 500 watts. I suggest goign more for liek a gold platnum or titanium 80+ PSU vs more wattage around 500 watts. 
 
as for the CPU. right now unless you are going at the absolute high end (IE a 9900k or kf) then AMD is the winner for gaming. R5 3600 is more efficient and more powerful than Intels i5 offerings. I run an i7 myself because at the time the 8700k was for the price the best option. if i were building today it would be a Ryzen 7 (i actually just built my son a pc and used a Ryzen 7 instead of an i7 for this reason) 

Guys i need good motherboard with 4 ram slots for i5 so i can easily overclock cpu and gpu
