That's what I thought and they start at like 1.86 GHz or something for a desktop and I upgraded it a few times to get the 2.4. The only thing higher I saw available was the 2.6 GHz but seeing as how I don't even need the 2.4 I stuck with that

I probably upgraded everything more than I needed to, but I love to get "cutting edge" that also fits in a college students budget.
