MSI X570 godlike are over £1500-2000 right now used and new stock (over 6-8 months ago you could find maybe new stock from real retailers but in USA only for around £700-750 to UK, not anymore they are £2k new now) because they are EOL and anyone selling one for £600 is either selling the engineering/preproduction samples that are faulty and when you update the BIOS they will never work right again too or just a faulty board or selling the Z490 Godlike for £600 which is the right price for them right now new and sending z490 and not a x570 Godlike.
They have a known fault the ones that were sent to reviewers and were not told they were engineering/preproduction samples, they start to fail after about 100-1000 restarts or reboots. So careful if someone offers you one for that, they are easy to spot the engineering samples as they have a test pins/port on the back of the board and have had some components changed due to the faults, the ones that were sold to customers didn't have the fault. So be aware of that as people are selling these engineering/ preproduction boards.

There is another 4 slot spacing x570 coming out the asus one here but you need to make sure your case will work with it as the slots are one slot lower than the msi godlike and may not fit in some cases with psus right under the motherboard or a shelf or separator area for the psu there, my setup with 2 x 3090s and the msi x570 godlike showing if it was one slot down more the card would hit the shelf that seperates the psu part from the motherboard area
