I have been playing the EA version of BG3 on the following PC:

Device name DESKTOP-A2PK36L
Processor Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz 2.80 GHz
Installed RAM 16.0 GB (15.9 GB usable)
System type 64-bit operating system, x64-based processor
GPU: Nvidia GeForce GTX 1050 Ti

I note in the minimum specs for the game as outlines below we are supposed to have a SSD.

Is having played the EA any indicator that my current PC will be adequate for BG3 upon release?

Processor: Intel I5 4690 / AMD FX 8350
Memory: 8 GB RAM
