Have this build waiting 90+ days for the 3080 and am now wondering if the 5800x would be a better processor (only a few quid in it) and just thinking I should ask here with all the guru's lurking rather than get lost on google again!

The 5900x would be nice but at circa £300 more (I'm ordering 2 of these) is a bit too lumpy.

This will be paired with a CRG9 and used for gaming + heavy productivity (dozens of browser tabs + multiple spreadsheets + databases) and graphic work.

Am upgrading from a i5-3570k rig which has been brilliant but aging badly and that awful spinning disk on Excel is now a daily occurance.

TIA

For gaming the 5800X will blow the 3900X out of the water, on multithread workloads, the 3900X probably just about pips it. Personally i’d go 5800X, but in some scenarios the 3900X will really be worth it, but yours doesn’t look to be TOO heavy, that the 5800X wouldn’t be a fine fit.

Completely agree, 5800X would better fit your uses with better single core speeds for gaming, and still monstrous multithreaded capabilities for the rest.

3900x you'd be sacrificing gaming performance and it wouldn't be as well balanced.

Thanks folks, that's the way I was leaning but didn't want to lead opinion when asking

There are a few other changes I'd make to that system while you're at it. I'd want a better motherboard and a better power supply at the very least.

I'd also question the overclocking: AMD processors don't gain a lot from it. Personally I'd think you would get a better overall build if you were to go for a non-overclocked 5800X, faster RAM and a faster boot drive. If you were to go down this route, you'd need to call PCS to change it and keep your place in the 3080 queue. It comes out as £8 more (though that's by going down to 1TB on the Firecuda).

If you were to stick with the overclock, I think you want a better motherboard (the X570 is what you want, really) and a better cooler (I'd want the H115i.

But here's my suggestion:

Appreciate this feedback

I've been able to nab a couple of these for my 2 builds.

Will do a bit of a further read up on the other points you raised.

Thanks again,

That's the ultimate in SSD luxury! To be honest, it wouldn't strike me as ideal. I would want one of those, and a 500GB one to use as my primary boot drive. In some ways, it's actually better to have a smaller primary drive because it will stop you filling it up and therefore make it easier to do things like re-installing Windows every now and again. (Sounds a pain but isn't, and is definitely worth doing.)

That said, there's no point in getting two 980s with that motherboard. The 980 uses a PCIe gen 4 slot, but the B450 chipset only offers one of those. You need an X570 motherboard to make the most of two 980s. (To be accurate, they will work, but at the speed of PCIe gen 3, i.e. equivalent to a 970.)

Apologies, I wasn't at all clear and thanks for checking.

I've two PC's waiting to be built, 1 x 980 each.
