I guess they're built using a smaller manufacturing process? Yeah though, When I was looking at different HP computers (tradition), the other decently powerful one, HP Omen, ran at a frequency 5% higher (2.6GHz), but was a 20% speed increase. (I'm not even sure how if they have the same processor architecture, but whatever.) However, it was $200 more, so I decided it wasn't worth it. I later found out the ram on it is soldered to the motherboard, so I'm really glad I didn't buy it now.
I've always had a sort of stigma against Dell (The only Dell computer I had had the hard drive break only a few years later) but it seems they offer the most powerful laptops for the best price. I saw a 3.5GHz one (I didn't even know they went that high) for $850, which I think is great. The way I see it, the faster the computer, the less you have to change them out (aside from the Dell, none of mine have broke; the processor would just become obsolete, and it's not like you can replace them.)
I've said this before, but I'm still really curious about this:
I guess this motherboard is used in a different laptop that had a designated GPU. This idea is even dumber than the hole drilling one, but I wonder if I could have someone with professional tools put a GPU on there (along with VRAM). At that point, it would probably be better to just get a new computer.
