Most laptops have unupgradable CPU
This isn't true. Most laptops have a removable CPU, the big exception these days being Macbooks.
As far as 3GB is plenty for most people, you won't notice much of a difference between 3GB and 8GB unless you're doing something RAM intensive like CAD, graphic design, etc.
The problem with upgrading a GPU in a laptop is that is that laptop motherboards are custom designed for the specific series of laptop with the GPU being custom designed for that motherboard (if not fully integrated into it), and the only time you'll see the possibility of upgrading is when there are other laptops in the same series as yours with better GPUs.
Further complications arise when you're trying to upgrade a newer model laptop. Typically laptop manufactures won't sell you a GPU by itself, which means you'll have to go through a third party. For older laptops eBay is a good source for this type of specific part, but since it's a newer model you probably won't see any just available just yet.
