That depends on what you're currently using.
Going from wide, knobby, wire bead tires to skinny kevlar slicks will definitely make a noticeable difference, but switching between otherwise similar tires probably won't.
Shaving a thousand grams from a wheelset will have a palpable effect, but shaving a hundred won't.
IOW, if you want to feel a difference, you're probably going to have to change something pretty significantly.
How much do you want/expect your "overall speed" to improve? In general, upgrades aren't going to take you from mid-pack to podium, so what are your goals here?
