Gaming at 3440x1440 with £1200, is this good enough?

[Wiald]

Putting together an new build from scratch and wanted some advice about motherboard, GPU, PSU and overall balance. I mean to do single player RPG gaming like the Witcher III on a 21:9 35" monitor at 3440x1440, which I am also yet to purchase.

Specs as follows:
CPU
AMD Ryzen 3 3300X AM4
or
AMD Ryzen 5 3600 Processor
Leaning towards 3300X bc cheaper and similar performance

MOBO
ASUS TUF Gaming X570-Plus
or
Gigabyte X570 AORUS ELITE

RAM
G.SKILL Ripjaws V Series F4-3600C16D-16GVK 16 GB (8 GB x 2) DDR4 3600 MHz C16 1.35

Storage
Sabrent 1TB Rocket Nvme PCIe 4.0 M.2 2280 Internal SSD (is PCIe 4.0 worth the extra money?)
or
Silicon Power PCIe M.2 NVMe SSD 1TB Gen3x4


GPU
GeForce RTX 2070 SUPER (which one?)

PSU
SilverStone Essential 650W 80 Plus Gold
or
Cooler Master MWE 650 Bronze V2, 80+ Bronze 650W
or
Corsair CV650
or
Seasonic M12II-620 EVO 620W '80 Plus Bronze

Case
Cooler Master Masterbox NR600

All input welcome.

Thanks

Thank you for the welcome and for your insightful feedback!

My understanding is that B450 boards like the Tomahawk MAX are compatible with R3/R5 out of the box and do not require any BIOS update, am I correct?

Will the B550 mobo be available to purchase on the 16th, or is it that a release date and then the mobo will be available in 2/3 weeks?

Thanks!
