4 x 32GB DDR4 4000Mhz Options

I am putting together a Ryzen 9 5950x build based on a Gigabyte AMD Ryzen X570 AORUS XTREME which will be used for work during the day and gaming at night. I need 128GB ram as will be running some network lab software which is very memory hungry. I hear that the sweet spot for memory on the Ryzen 9 59xx will be 4000 Mhz. However im struggling to find any in 32GB sticks and the one I can find is £1200! for 128GB. I know the Ryzen 9 59xx is not released yet but will I really see that much difference in speed if I just go with 3600 Mhz? I can get VENGEANCE RGB PRO 128GB (4X32GB) DDR4 PC4-29200C18 3600MHZ QUAD CHANNEL KIT on overclockers for £530 which is a huge cost saving. Again with CAS 18-22-22-42 Timings is this a big issue? My gpu will be a Asus 3090 Strix OC (on order) if that helps, so I don't want to compromise to much on speed.

Thanks

Thanks for the info guys, the software im using will not really benefit wether I use 3600 or 4000Mhz my thought process was more not to compromise on the gaming performance of the machine given the gpu and cpu. I take your point regarding the capacity and speed there is very little choice and less so availability of 4x32gb 4000Mhz. Looks like G.Skill Ripjaws V DDR4-4000MHz CL18-22-22-42 1.40V can be had for the same price as the Vengeance Pro 128GB 3600Mhz with the same timings.

Ah yes I read that now. So If I was to go with 4000Mhz in the hope that I can overclock to that, would it normally have a number of XMP profiles so as to run at 3200 or 3600 if thats all I can achieve? Looking at memory it was not obvious to me if lover XMP profiles are supported under the native speed. Cheers!

Doing a bit more research and understanding the above a bit more I see that 4000 Mhz would be its max rated speed out of the box in terms of XMP profiles, so would assume would support other lower profiles
