Yes, you can tell if you know about it. No, you don't notice that if you have no idea.
You can compare it roughly with a Ferrari and a Porsche (in terms of speed). The Ferrari, for example, drives max. 300km/h, the Porsche max. 250km/h. However, if you only drive at a maximum of 200 km/h (on the German autobahn), it doesn't really matter, because both can drive at 200 km/h.
Counter question: What games do you play and at what resolution (what kind of monitor do you use)?
