Let's start with the monitor. You want 1440p, at least 144Hz, and either IPS or QD-OLED, depending on your budget.
Cheap: AOC Q27G4X at £180ish (IPS, 180Hz)
Value: MSI MAG274QRF QD E2 at £230ish (IPS, but better, 180Hz)
A bit indulgdent: Asus VG27AQML1A at £330ish (IPS, 240Hz)
Top-tier: MSI MAG...
One thing that will keep 1080p relevant is laptops. It doesn't make a lot of sense for a 15" gaming laptop to have more than a 1080p screen, and obviously that makes more sense for laptop hardware to run at appropriate frame rates. On desktop, it is only a budget option now, more for the...
Sorry, more questions! What kind of work? Web browser and office documents or something more intensive like 3D modelling or video editing?
What would you be willing to spend on a new display? (Personally I'd keep at least one of your existing displays to be a secondary monitor, while getting a...
Well I wouldn't recommend buying that one, but it'll do you a job for now. Ultimately it's quite a low resolution display by modern standards, and at some point you'll want to upgrade.
The system above will do a decent starting job at 1440p and could easily be upgraded to do it better if you...
I presume you already have the monitor? Not one I'd recommend but if you already have it...!
I'd look at a system like this. It's just over your £1400 budget but I think all the upgrades to your post are worth it. It makes it a much stronger system not only for the short term but probably for...
It would not be cheaper to buy a new build. But you might find it better value for money. You could easily spend £700 or more upgrading that to a reasonable spec, and you would still be on an old platform. That would be a hefty chunk towards a new PC.
Well unless you have work requirements that are extreme (3d modelling, video editing etc) you don't need 64GB, and it's expensive.
They will probably offer a 10-20% performance increase at about the same price, or the same performance for cheaper. That's a guess, but it's about where they've...
Did you change the case, @MatthewStubbings161? I don't get that comment when I go to build it, and moreover the board has the appropriate headers for that case.
There's a strong argument here to say "don't buy your PC now". In all likelihood, in the next few months there will be 9000X3D CPUs and 5000-series graphics cards out and they will offer a substantial performance gain. If you are able, I would hold off till then. However, maybe you're in a rush...
Yes, don't get that PC. The case, CPU, motherboard, memory, storage and graphics card (i.e. the fundamentals of the system) are all poor choices for one reason or another. It would perform significantly worse than my build above.
Ultimately, if you buy the PC I've posted above, you're getting a...
As an idea of what your budget is like, here's a £1500 build, probably the best you can get for that money. It has compromises on CPU and GPU (it would do OK for 1080p, but 1440p at high quality and high frame rate in racing games will not be happening), as well as storage. It's a decent PC, but...
Or get one of the Pop Air cases from Fractal (really pretty as well as practical) and do "send in your own case".
Realistically an internal DVD drive is now a niche requirement, so you really will be limited on cases and may have to go out of your way to get one.
With a slight edit to @Ekans2011's builds above, you could get a 16-core CPU and a better cooler, with a lower-tier motherboard. X870 is great, but I think it's questionable whether you'll derive significant benefit from it, whereas the 16 cores of the 7950X would be amazing for your purposes...
Here's what I'd consider the cheapest gaming system I'd consider to be worth buying. I wouldn't advocate it, as it's not going to offer the best value, and really you would be better off spending a bit more, especially on the graphics card. But it would work.

What's it for? What's your budget? What monitor will you be using?
Basically, don't buy this: it's not a good bet at all. You can do way, way better for your money.
