Both CPUs are going to be two generations old late this year/winter, but mobo doesn't support newer.
Also especially compared to Intel's "advance" those are major update from original Zen.
As for SSDs prices are now very good with consumer NVMe SSD costing no more than SATA SSD.
WD Blue SN550 1TB SSD NVME M.2 2280 PCIe Gen3 Solid State Drive (WDS100T2B0C)=
£89.99
WD Blue SN550 2TB SSD NVME M.2 2280 PCIe Gen3 Solid State Drive (WDS200T2B0C)=
£199.99
In 1TB size even high end drive doesn't cost much more:
Seagate Firecuda 510 1TB SSD PCIe NVMe M.2 Solid State Drive (ZP1000GM3A011)=
£104.99
In 2TB size price rises more, though Cordsair MP510 is now well priced.
Corsair Force MP510 series 1920GB NVMe PCIe M.2 Solid State Drive (CSSD-F1920GBMP510)=
£248.99
As for monitor only 4K would be genuine upgrade with common 2560x1440 being downgrade in vertical resolution.
I'm myself using similar Dell U3014 and hoping that 32" 144Hz 4K monitors finally materialize in coming months.
Thanks very much for the advice.
CPU - The reasons im looking at the 3700/3800
1. I would be saving around £150 just on the CPU if I went for the last-gen and I don't really need a lot more power yet.
2. If I went for the 5000 I would need a new Motherboard and pay more for the CPU,
3. The 6000 I don't know much about it but I'm assuming it will be the new AM5 also assuming I would need DDR5 not DDR4 and the cost is still unknown.
4. I would still be bottlenecked considering I have a RX 580
This was my thoughts on the CPU but I'm open to advice
SSD - This is why I was hoping for an NVMe to start I may get an SSD also at a later point because my board only has 1x m.2 port. I'm hoping a good sale pops up.
Monitor - My monitor has some good specs the only reason I was thinking of upgrading as it is a little dated and I not very clean when it comes to movies or games, it has that standard 17" monitor look
Any other advice is welcome
