Hello everyone, getting ready to do a complete new build to upgrade my existing gaming system.

I'm coming form a Ryzen 2700X, 32Gb RAM and an RTX 2080 which has done me well since I put it together 5 years ago but is starting to drag its feet in modern games and I've put off upgrading anything inside of it to the point that I think a totally new build is going to be the way to go.

I play a variety of games, current monitor is a decent 27", 165Hz ,1440p one but I think that will get upgraded to an OLED this year, maybe along with making the jump to 4k.

I'm trying to keep the total spend ≤ £2.5-3k, but suspect the premium for the CPU and GPU at the moment will push that to the upper ends of that range, I generally don't upgrade or tinker too much once I've built my machines so prefer to spend now on higher end / well built components.

I have the below parts list at the moment which will be paired up with an RTX 5080 when they become available. I know lots of things are also out of stock / pre-order / back order so I was just going to pick them up as and when they become available and hopefully have all the bits together ready for when the 5080 go on sale.

My basket at OcUK:

Case: I really like the aesthetic of the North, I'm not a fan of cutout windows or RGB lights so the mesh one suits me fine. I've gone for the XL version as it will have better support for long GPUs and should fit the Arctic AIO up top without a problem. I did also like the look of the Antec Flow Pro but I don't think they do a solid sided version of that case and it's also a bit bigger than the North XL which is already a bit bigger than my current Define R6!

PSU: Not sure if I need 1000w, I've used Corsair or Seasonic PSUs in the past but open for other suggestions. Selected this one as reviews seem generally good for it and the included cables look decently flexible, I've got an HXi 750w in my current machine and that has also been good.

Mobo: I was looking at the TUF Gaming one but that is quit a bit more expensive than the Tomahawk. Am I better off hunting around for a good B650E board instead - I'm looking around for something with a PCI-E 5.0 slot for the GPU, at least one gen5 slot for the primary m.2 drive and then 2-3 other gen4 m.2 slots, I don't need it to have Wi-Fi as my house is wired with Cat6, though it seems that most of the mid to high-end boards come with it regardless.

CPU: 9800X3D, Not really sure there is any other choice until the next model up releases? :-)

RAM: 32Gb DDR5, I've read that 6000MHz C30 stuff is generally a good balance for price, performance and reliability and as I don't need or want RGB bling this kit seemed to fit the bill.

CPU Cooler: I actually already have this as I got gifted it by a friend who rebuilt their PC with a custom loop recently - it is a chunky beast so if I struggle with clearances in the case my backup plan is to swap the supplied fans for some slimmer ones (Arctic P12 Slim perhaps).

Drives: New fancy 2Tb drive for OS + games I play frequently, I will bring over 2x m.2 NVME from my existing system (Evo 870, 1Tb) to use for other storage, I also have an old 1Tb SATA SSD that I will chuck in the back of the case.

The main difference with X870 is USB4, though ASRock's X870 Pro RS is a similar price to the cheaper B650E boards and performed well thermally in HUB's roundup (is 8-layer too, which likely helps with that). B650E and X870 are otherwise identical, apart from a newer shipping BIOS with the latter.

X670E/x870E is likely to have better support for running 4x M.2 drives, the USB4 on X870/X870E can impact the available lanes for M.2 or the graphics, because they tend to take CPU lanes to do it.

I've got a similar spec and currently designing my upgade path so keen to hear how you enjoy the new rig! Couple of thoughts.

- PSU I'd go 1000W. Your 750W will probably work with a 5080 but 850W is the recommended minimum so I'd not risk it.

- Mobo - Any reason for not waiting for B850 release? They do everthing you need and have less issues with lane sharing than the X870. Except no USB4. The no wifi versions also lack Bluetooth so might be worth getting a wifi versioneven if cabled. Could save £50-100.

Asrock entry level = £157
Gigagyte Aurus Elite EWifi7 = £214
 

That's a huge case. Do you really need such a large case? Take a look at the Montech King95 Pro and the plain Fractal North.


Given how long you keep your PC, perhaps 64 GB (2x 32 GB) might be of interest. Which games do you play?

Yes, wasn't intending to reuse my 750w PSU as will need it to keep the other system running for a while anyway and as you say it is below the 850w min recommendation.

I had looked at the B850 boards and they are starting to become available to order though the ones with less compromises don't seem to save that much and having USB4 may be handy in the future I suppose. Hadn't noticed re the bluetooth on non Wi-Fi ones so thanks for pointing that out, again not a thing I use really as my headphones and keyboard are connected with good old fashioned cables and the mouse has its own propriatiry dongle.

So the case I really wanted to build in was the Lian Li SUP01 but I'm not sure whether I want to find out if the long riser cable that case uses will give me any problems with a new 5080... or am I over thinking this?

If I could fit things into the regular North that would be nice, but it won't fit the Arctic AIO that I already have up top, and if I front mount it then it will reduce the GPU length considerably from looking at the docs on Fractal's website - the Arctic is also a chunky bugger as it uses a 38mm rad + the stock 25mm fans so 63mm total depth so in the regular North front mounted the GPU cannot be longer than 317mm.

Looking at a couple of the AIB 5080s they are all ≥300mm and most seem to be ≥330 so either really close to that limit or simply wont fit.

I'm not wed to using the Arctic 360, aside from I already have it (freebie from a friend) and by all accounts is an exceptionally good cooler.

Dimesions wise the North XL is a bit shorter than my current R6 but a little bit taller - looking at the Montech (though I'm not a fan of the looks of that personally) whilst it is shorter and lower its a lot wider which would take up a bit more space where I have the tower located at the moment than I'd like which was a common factor ruling out a lot of dual-chamber type designs for me.

i am mostly playing things BG3, DRG, POE2, HD2, Satisfactory at the moment so for RAM I think 32Gb should be fine for me, I have 32Gb in the current system and it never really gets above 16-18Gb utilisation so I figurd I'd save the money for now as its around £100-120 more for a 64Gb kit over a 32Gb kit it seems.
 
So pushed the button and ordered most of the bits from OcUK this morning as they had the X870 Tomahawk in stock though those are back to pre-order now, hopefully I got in before they ran out - guess I will find out if I get a shipping notification later today.

Dropped the main m.2 drive down to the WD Black as suggested above to save a few quid, and I orderd the Corsair PSU elsewhere as they were in stock at the same price so with any luck I should be able to put this togehter over the weekend and then it will just be a case of getting lucky on the 30th for a 5080.

I was thinking of dropping my 2080 into the new box so I can power it up and do some teting on the CPU and RAM at least, cannot see any reason why that is a bad idea and then just swap it out when the new one arrives?

Yeah there's not an issue, but you don't need it, since it'll work through the mobo outputs anyway (since 7000/9000 CPUs have integrated graphics).

Hadn't realiesd that, currently installing Win11 on it then need to bump the BIOS I think before doing any testing - I'll probably still drop the 2080 into it later before the 5080 arrives though :-)

Case was pretty easy to build in, loads of space even with the chunky Arctic cooler up top.

The motherboard had an extra PCI-E power connector on it, wasn't quite sure what that was for to be honest as the manual is a bit vague saying it is for "high power cards" though I did wonder if maybe some of the USB-C ports take power from it for PD. Had plenty of spare cables and outlets on the PSU though so plugged it in just in case.
