Originality-does it matter?

Just curious as to what you guys think about originality when it comes to restoration projects...I've seen some absolute stupid numbers pop up at auction, some in excess of 40k. Sure, I get that. A collector wants a car that is perfectly restored right down to squiggly numbers scrawled on parts with a paint pen, and will pay beau coup bux to get it!...but for the average Joe, how much do things like matching numbers and paint codes and original equipment really affect value? For example, the original motor and trans are long gone from my car, probably blown up by the original owner. Is having paint that doesn't match the fender tag that big of a downer? Stuff like that.
Now I realize that when you buy a car it's yours to do with whatever you wish and to hell with everyone else, but curious to hear other people's take on this? Thanks!

If it's a HP car.. I like to see all the original equipment with the exception for a few things of course, like intake manifold perhaps if it's just an iron four barrel that's pretty common. If it's just a car that's been upgraded, bigger motor ,stronger Parts.. stuff like that.. as long as it's Mopar stuff or good aftermarket, I'm good.
My 67 Signet was a slant car, but I dropped a 340k frame, disc brakes, a four-speed and a 340 into it and backed it with an 8 and 3/4. It's all Mopar stuff down to the intake manifold being Edelbrock with a Chrysler part number. Only Exception is headers instead of the exhaust manifolds, though I have those 340 exhaust manifolds too.
I basically like era correct and factory mopar equipment is what I should say
