High speed in the is boils down to one thing. How close you are to a larger city. Majorty of large cities and out lying area's, as well as smaller cities are fine. But if you live out in the country.. you have a "chance" to have high speed.
My friend use to live in area where he can't get cable (reason why dish / directTV do as well as they do in addition to being cheaper).
If broadband via power lines takes off, this could help out but seen very slow adoption. WiMax (a tower with 30 mile high speed wireless internet access) is still too up in the air and the fact that WiMax is competing with Telephone/Cellphone and Wifi hotspots...
I am not sure about the dialup, but if you payed for broadband or something, then you could sort of call that the GW monthly fee, and everything would be faster. Other than that, repeating what everyone said, your system specs pwn. I would go for it anyway.
