You have the 18 R1 laptop. Windows 11 is not supported by Dell on this model. You will have to search non-Dell sites for spare parts.
You have the AMD Radeon R9 M290X 4GB GPU. The CXC7W Nvidia GeForce GTX 880M N15E-GX 8GB GPU was the best we offered. 79HD4 Intel i7-4940MX 3.1GHz was the fastest CPU.
Hello, just like Chris says, the 4940MX is the best CPU option for the 18, this is limited to the CPU socket so there is no chance of installing anything more recent than the 4th gen mobile CPU's.
The GPU options are almost endless. Some people have been testing MXM RTX 4090 cards in these system with some success so it really depends on how far you want to go (how much you want to spend).
Even with a well overclocked 4940MX, you will not get the full potential out of a card like a 4090 so there are some diminishing returns as you go higher in the GPU range.
I believe there are RTX 3050/3060 MXM cards available so these would be a really good sweet spot for your system. A place called x-vsion sells all kinds of MXM cards. Some modifications may be required and usually a custom heatsink is also needed.
The NotebookTalk forum would be your best bet for all the information you need.
Win11 is not officially supported on these old systems but there are ways around it.
@Waldo Camper You could probably upgrade your 18 and end up with a pretty decent system for under $500USD but that money could be better invested in a new(er) machine.
But, there is still a small community of guys who still tinker with these older laptops, if you want to fall down that rabbit hole.

@DELL-ChrisM2
Thank you for the information. It looks like I would be better off just buying new rather than replacing parts. Have a great day.
