I`ve been thinking switching to PC after this weeks news
Processor AMD Ryzen 5 4600H with Radeon Graphics 3.00 GHz
Installed RAM 20.0 GB (19.4 GB usable)
System type 64-bit operating system, x64-based processor
I did check - (can you run it) and says i could run elite with min specs and recommended.
I am not too sure if it will, and not sure that website is 100% accurate

Unless you have a dedicated GPU in there, this system is not going to provide performance many would find acceptable.
That "19.4GB usable" might indicate that the integrated graphics are not being used, but more info is needed.
What's the exact model number?
Yes, I would think so. One stat jumped out at me:
...sounded like a strange amount of total memory. Memory chips come in 1,2,4,8,16,32 etc Gb sizes (you get the gist). To add up to 20, I'm guessing there's perhaps a 16Gb and a 4Gb installed? Normally if you were building a PC you would stick to using the same sizes together. This probably isn't an issue, just making an observation.
You are actually using a 16 GB and a 4Gb stick? That must hurt your performance.
Either 4GiB preinstalled as a DIMM or soldered directly to the board (very common in budget laptops) in the first channel and a 16GiB DIMM in the second channel (and possibly only actual DIMM slot).
The main concern with memory performance on this platform is feeding the integrated GPU and an asymmetric configuration doesn't really hurt here. The first 8GiB of memory is fully dual-channel because each channel is interleaved as far as is capable. Only physical address space past 8GiB is single channel, and since the IGP is going to reserve 2 or 4 GiB on start up for it self, the video memory should always be dual-channel.
If there is a dedicated GPU, then memory bandwidth is much less of an issue. Anything in the upper 12GiB of physical addresses will be slower, but it it's not likely to be a bottleneck for the system.
