Is it possible to upgrade the Processor and/or Graphics Card of a Samsung r580 laptop?
You probably can, but it won’t be easy, and it won’t be cheap. If you don’t have experience with repairing laptops, I’d say you would want to take it to a repairman to have that done, because replacing the processor is one of the hardest things to do with a laptop. The price of the components plus the upgrade price from a repairman would probably end up costing you as much as a new decent laptop. Therefore, I would suggest you shouldn’t do it, particularly since I noticed that your processor is quite nice anyways. An upgrade to an i7 processor (the only upgrade I know of at the moment) would be expensive, and a graphics card upgrade would probably be expensive as well.
