blckhaze went over your budget. I would go with the first system (SAAIELLO), because you do not need the slightly better CPU from the second and it has more up to date technology. Plus the performance increase provided by the $26 more phenom would not be all that noticeable. Especially considering the quad there is $99. That is impressive. I didn't realize prices had dropped so much.
I'd get this motherboard though:http://www.newegg.com/Product/Product.aspx?Item=N82E16813131406
More room to upgrade your ram as needed.
