3700x or 3900x? Is the 3900x Overkill?

[xNDx]

Hi Guys!

 

I've finally got a build locked down that I'm happy with. After getting some help the other day from the forum, I've decided to switch my build over to AMD rather than Intel. Now, I'm not too sure which CPU I should purchase for my needs - Photoshop, Video Editing, Photo Editing, Multi-tasking, and Gaming. While I plan to game on the build, I'm not overly concerned about losing a few frames as I'll still mainly be using my consoles. 

 

Having used an i7 3770 for the past seven years, I'd ideally like to have a computer that lasts. Now, is there a great difference between the 3700x and the 3900x? I'm trying to stick to a $2500 AUD budget, so going for a 3900x will mean that I can only purchase 16gb, whereas the 3700x will allow me to run 32gb with my budget. It's also worth mentioning that I don't plan on doing any overclocking and would prefer to keep things as simple as possible.

 

I'd love to hear your opinions on which CPU I should purchase. Also, if there is anything you think I should change with my build, please just let me know.

If your primary focus is gaming, than 3700x is more than enough. If work is more important, then definetely go for 3900x, as it won't be near maximum amount of cores workstation software can use.

[Jimkirk363]

If you are going to be using 32GB ram with the 3700x i say this would be more than adequate. I have 32GB with my 2700x and it works wonders.

[LukeSavenije]

please don't buy that board... rather a b450 tomahawk than that

[Akira Shimazu]

well for me 3700X 32GB is better than 3900X 16GB.

 

i meant like 3700X with 8C/16T 4.4Ghz is like really powerfull.

@xNDx

 

looks good! As @LukeSavenije mentioned grab a different board. B450 tomahawk is a good choice.

 

unless you need pair gen 4 of course - grab a better X570 board.

Why not that board? This was recommended several times yesterday.

I won't necessarily be doing anything too hardcore - ie gaming or working with 4k videos etc. If I was to go with the 3900x and use 16gb, I could always buy another stick when I can afford it. I'd like the computer to last at least 5 years, but I also don't want to be a complete overkill if it's not needed.  Hahaha, who know planning a build could be this stressful.

Is there any real downgrade between the two boards? Will I have problems in the future? I've noticed it's about $70 cheaper. Not sure if that's a bad thing.

Asus: X570 Prime-P, X470 Strix-F, X370 Crosshair VI Hero, Strix-F

Asrock: X570 Extreme4, Steel Legend

Gigabyte: X570 ITX

MSI: X570 Gaming Pro Carbon, x470 gaming pro carbon

 

some of these will be better suited for a 3900x

funny then... it's the x470 master/sli vrm with doublers, so the second worst on x570. do you need pcie 4? otherwise you can pick up something like the b450 tomahawk or pro carbon for much less

hm... i know that list from something

 

(it's worst case btw, p95 full stress)

 Copy paste .

 

but the board he has chosen would be fine for the 3700x I’d say, 3900x might be a bit stretching

To be completely honest, I don't really know what pcie 4 is or what it does. I don't really know much about computer specs, it'll be my first build by myself.  From the list that @Stormseeker9 suggested, I think the X570 Prime-P is kind of my budget as it's almost $300.

I have just finished my Ryzen 9 3900x build, I am primarily using it for games. The x570 mobo chipset is good but still in early stages and i had some issues with my ddr settings and getting the pc stable even using stock xmp. After some playing around and bios updates, i have it running perfectly. From what i have seen the R9 3900x is great for future proofing and only $100AUDish more then the Ryzen 7 3rd gen. Just look at some reviews on the x570 mobos for what you prefer. Im currently using the Gigabyte Aorus X570 Elite, 16GB ddr4 3200Mhz.

it has a higher bandwidth for GPUs, storage and so on

 

but there are not that many devices that support it as the time of writing

[xNDx]

So I've done some research and found that the MSI MPG X570 GAMING PLUS AMD AM4 ATX has some pretty decent reviews. I found that the Asus board had quite a few people with bios issues, which I would like to avoid.

 

Here's what my build looks like now. Also, I read in a review that some of these motherboards only allow certain PSU's as they require a certain pin. How do I know if it's going to be compatible? I decided to spend $10 extra on a 650w psu, just to ensure that I have enough power.
