I'm looking at laptops for college and I was on the Dell site (gasp!) to see what their cheaper laptops had to offer. I was pleasantly surprised when I saw that all their laptops offered i7 processor upgrades if one wished to upgrade. But then... I noticed that the processors clocked at 1.6 GHz. What's up with that? The MacBook Pro i7's come in at >2.4 GHz. Are Dells just cheap little bastards or what? Anyone care to elaborate on this seemingly huge difference for the same processor? Also, can anyone give an estimate on how noticeable the difference between a 1.6 GHz and 2.4 GHz processor would be?
