Upgrading in secret, shhhh

Hey all, I need help! I'm upgrading my son's computer without him knowing.

Current PC (Omen 870-224):
Processor: Intel core i5-7400, 7th is,
Memory: 8GB DDR4-2133
Graphics Card: NVidia GeForce, GTX 1060
Mobo: HP
PSU: HP 80 plus Bronze, 500W
Screen: MSI Mag272R

Looking at upgrades:
Memory: Corsair Vengeance LPX 2x8GB, DDR4
Processor: AMD-Ryzen 3700X, 3rd Gen
Mobo: ASUS Tuff Gaming X570-Plus

I have a budget. I was originally only going to add the memory, but I think everything else needs a boost.
I'm getting stuck on the graphics card upgrade now and reconsidering everything. There's no more GPU DDR4 really made, and I'm only finding GDDR5 and GDDR6, not knowing if they are compatible. Appears DDR4 is obsolete. For GPU was looking at Nvidia GeForce RTX 3060Ti Founders Edition or AMD Radeon RX 5700XT.

Any suggestions would really help! Or if I'm doing a good job, encouragement. Lol! Thank you!!!
Hi nice of you to upgrade your sons rig! I can see you've been looking into it but you seem to have a couple of wires crossed. I'm sorry I'm going to really rain on your parade but this is kind of how it is at the moment.

System RAM is DDR4 and is not obsolete, graphics cards have GDDR5/6 RAM etc, these are totally unrelated and compatibility between them is not an issue.

The CPU and RAM are a very good choice.


Motherboards off the shelf come in standard sizes with the same hole placements for compatibility with DIY cases etc. OEM machine makers sometimes use bespoke parts that are only compatible with the cases they use. I found a forum post which suggests that the case you have uses a standard Micro ATX (M-ATX) sized motherboard. You need to really double check and make sure that's actually the case, if its a proprietary size then you cannot change out the motherboard.

The board you listed above is a good one, but unfortunately ATX sized which is larger and so wont fit in your case even if it is M-ATX compatible.

Another problem is the state of the graphics card market, its almost impossible to find cards for sensible prices at the moment so I cant recommend anything right now. It's set to last until at least next year if predictions on chip supply from experts turn out to be true.

The 500 W power supply you have in that machine will also not be enough to reliably run any of the 3000 series Nvidia cards, or any of the current AMD 6000 series graphics cards, even if you could find one for MSRP. Also the physical size of your system will limit the card that you can fit inside, even if you could replace the power supply. Higher end cards have large heatsinks and coolers that don't really suit small cases well, if at all.

Finally, the copy of Windows 10 that come with your machine will be an OEM copy. That means when you change out the motherboard your license will no longer be valid, and legally you would have to buy a new one.


A) Find a second hand 7700K to install. I wouldn't pay more than 200 USD absolute tops. Add in a second stick of cheap 8GB DDR4 RAM, with the motherboard you have it will not run faster than 2133 at standard settings so anything will be fine, and should run without issue. The 7700K will be noticeably smother then the 7400K in many games, and the extra RAM will also help a lot. I would also suggest an SSD, see below.

B) Keep researching parts, save up the money for a year until graphics cards are more reasonably priced again, and build a system from scratch that will not have any of the above problems. At that point you should be able to put together something for $1000 that will provide a much better experience overall.

C) If you are set on the Ryzen 3700, new motherboard, RAM and new copy of Windows, and it will fit in your case. Something like this would be a good start, and carry over to a new build later on. The SSD is a must in 2021, the difference it makes to using the machine overall is not worth missing out on. I would go for a 1 TB model but I'm not sure on your budget and 500GB is enough for Windows and a game or so depending on the install sizes.

This is all great info!!! Thank you so much!!
I noticed the issues with the case myself and opted for a DIY build if you will. He has a 1TB SSD currently in his set up that I can move over. I also noted the power issue and looking at 850W 80Gold plus something, I think it's called.
