Upgrade Older System Worth it?

Posted by OleElGrande@reddit | buildapc | View on Reddit | 16 comments

Plan is to move from this:

Fractal Meshify C case

Gigabyte B550 Aorus Elite AX V2

16GB RAM DDR4 3600mhz (2x8gb)

Ryzen 7 3700x

RTX 2060 6GB

EVGA SuperNoVa 750 G2 80+ GOLD

DarkRock Pro 4 CPU cooler

Rzyen 5800x3d (or cheaper option?)

RX 7900XTX

32GB RAM DDR4 3600mhz (2x16gb)

--rest remains same--

Is this a sensible upgrade that will last me another 3 years or so?

*IF* AMD relaunches the R7 5800x3D (as is rumoured) and it comes in at a decent price (eg: under $300) then that is a decent upgrade path for the 3700x (along with 32gb of RAM) in the scenario where you don't want to upgrade to a DDR5 platform.

If you have to pay current scalper prices for the 5800x3D then no.

If your PSU can still handle the 7900XTX despite years of slowly degrading ... and you specifically need the extra 8gb of VRAM over a 9070XT ... then that might be worthwhile, but I'm dubious about the PSU still holding up to such a high power card.

So a fresh new build would be best?

I did purchase a 7900xtx recently for a good price yet to install it.

Worth trying it to see if it runs at all with your PSU, but I have a suspicion that you'll struggle. I had an older Corsair RM750 Gold rated PSU from my rtx3070 system and it seemed to handle the 9070xt at first if I undervolted it, but eventually couldn't handle and I had to upgrade.

You should do more research. The 5800x3D is about the same as an R7 7700x in general, with a few games that heavily favour one or the other.

Ok, bought a 850w PSU (NZXT c850), will update RAM to 32gb and will wait another short time to upgrade CPU.

I'll keep an eye on prices CPU wise, some suggesting my 3700x will do fine for now (4k gaming mainly so 7900XTX does the heavy lifting?)?

yeah, that's a smart move. I've currently got a 3700x and a 5900x, and have tried both at 4k, and the distance between them shrinks significantly at high resolution.

If you can get a 5800x3D for cheap enough, it will be good, but you might be sufficiently happy with the 3700x or even a cheap 5700x upgrade one day, but I wouldn't put as high a priority on the CPU as you are doing with the RAM and GPU.

You're making the right choices IMO.

Thanks, thats v reassuring. I also hear the 10th anniversary 5800x3d may be a reasonable price given AM4 is EOL.. I am crossing everything for that as 2nd hand market has exploded for them.

Might want to upgrade the PSU as well - all AMD setups will boost up CPU/GPU simultaneously (850W min, lower end 1000W would be OK..)

OleElGrande@reddit (OP)

At that stage is it not worth just building a more modern new build completely?

What monitor do you have? (that’ll largely dictate what upgrades you’ll make..)

Dual set up:

Gigabyte M28u (28" 4k 144hz) and another 144hz 1080p monitor Asus 27"

Given you have a 7900XTX on credit already I'd probably say to use that and a larger PS alongside your 3700X and see how it holds up (upgrading your CPU isn't necessarily going to give you too much extra with a 144Hz cap..)
