> "32 GB DDR4-2933 SDRAM (2 x 16 GB)" for the RAM + 32 GB Intel® Optane™ memory" for the SSD and "1 TB Intel® SSD.
Those are "high-end" specifications for those current parts, as is typical for any "gaming" computer.
Before you spend any money, launch your game, play it for a while, and then launch the Windows Task Manager, and switch to its "Performance" tab. You'll see how much of that 32 GB of RAM is being used, and how much is NOT being used.
Also, hold-down the "Windows" key (bottom-left of your keyboard) and tap the "E" key, to open File Explorer. Release both keys, and right-mouse-click on the icon for the "C:" disk-drive. You will see a pie-graph, showing how much of your 1TB of disk-space is currently being used, and how much is NOT being used. If it shows that the "used" space is only 1/4 of the 1TB, then there probably is NO need to spend your money to upgrade it.
How many slots for RAM are present on the motherboard? Just 2 (both currently occupied), or 4 (currently with 2 empty slots) ? If you need to buy RAM, be sure to get "DDR4-2933" with the "Optane" feature, preferably made by the same manufacturer (ELPIDA? CRUCIAL? MICRON?) as the current sticks of RAM.
