No you won't, laptops are generally not upgradeable in any significant way. The only real upgrades you can do to a laptop are RAM, and swapping out the hard drive. CPU upgrades generally aren't possible because the motherboard's BIOS tend to have a very limited CPU support list. Graphics are only upgradeable if the laptop has an MXM slot, and only really high end gaming laptops have those, and even then not every MXM card will work in a given slot.
If you want upgradeablility, get a desktop. If you desperately need mobility, shell out as much cash as you can for the most powerful system you can get, because you will be stuck with what you buy.
