I hope you don't mind if I make a couple suggestions.
For either the 80 dollar or the 115 dollar AMD CPU, you might consider listing the Phenom II X2 545. Right now its 89.99 on Newegg, and not strictly an 80 dollar processor, but should be close enough. It also falls only 0.1ghz behind its big brother, the X2 550. Very nice processor for the money.
There is now a 95 watt variant of the Phenom II X4 945. I can't find any reviews on it, but supposedly it is just a lower power version of the old 125 watt model. They can both be posted together, as they likely perform similar. They are also very similar in price; in fact, the new version is only 179 dollars and currently on sale for the 125 watt's 169.
