Optimise for new build?

[Littlenose]

I'm building a new box for the upcoming 9800x3d release.
It'll primarily be for flight sims, and think I've picked out suitable parts, but wondered if it could be optimised by spending a little more, or even by choosing something cheaper where I'd not lose anything perceptible?

This is my shopping cart at the moment:

1 X Asrock X670E Pro RS (Socket AM5) DDR5 ATX Motherboard - £279.98
SKU: MB-18S-AK

---

1 X G.Skill Trident Z5 Neo EXPO RGB 64GB (2x32GB) DDR5 PC5-48000C30 6000MHz Dual Channel Kit - £230.00
SKU: MEM-GSK-01357

---

1 X Antec C5 ARGB Midi Tower - Black - £109.99
SKU: CAS-ATC-02729

---

1 X Lian Li Galahad II LCD Performance AIO 280mm CPU Water Cooler - Black - £129.95
SKU: COO-LIA-00529

---

Grand Total: £749.92

I have a new 1000W power supply ready to go in.
I'm borrowing a 3080Ti, and stealing a 2TB nvme from my "old" box.
Will likely end up with 3 nvme's, and a 5080 (or 5090) next year.

How much cheaper do you want to be?

Here's one combo:

My basket at OcUK:

• 1 x Asrock X870 Pro RS WIFI (Socket AM5) DDR5 ATX Motherboard (SKU: MOT-ASR-03308) = £220.00
• 1 x Corsair Vengeance EXPO 64GB (2X32GB) DDR5 PC5-44800C40 5600MHz Dual Channel Kit - Black (CMK64GX5M2B5600Z40) (SKU: MY-4DL-CS) = £158.98
• 1 x Phanteks Eclipse P400S Glass Midi Tower Case - Noise Dampened Gun Metal (SKU: CA-06A-PT) = £54.54
• 1 x Thermalright Peerless Assassin 120 SE ARGB Black CPU Cooler - 120mm (SKU: COO-TLR-02724) = £29.99

Total: £475.50 (includes delivery: £11.98)​

You would lose a little performance with the slower RAM, but since X3D CPUs are not very sensitive to memory speed, I doubt you will lose much.

The motherboard has 3 M.2 slots so fine with your planned 3, but that's 2 down on the board in your spec.

If you don't care about PCI-E 5.0/USB4 you could get an even cheaper B650 board with 3x M.2.

Thanks for posting up some options. The info on the mobo is really interesting.
Will I not need PCI-E 5 for the Nvidea 5080 in the coming year ?

The 4090 (PCI-E 4.0) doesn't lose much performance in a PCI-E 3.0 board, so I would assume that the loss will be minimal, but I'd personally recommend you don't cheap out on the motherboard to that extent if you're going to spend £1000+ on a 5080. The board I suggested would be fine (has PCI-E 5.0 and USB4) and saves you £60, assuming you don't mind the lost lanes/M.2 slots.

My CPU is on delivery, and hte mobo market has fluctuated in stock quite a bit, I have ended up with the MSI MAG X670E Tomahawk WIFI motherboard.

Hoping to build this weekend, and will post successes / fails here
