Good laptop in the sub $600 range

Not sure if this is the right spot to I apologize in advance..

I am looking to get a new laptop for my dad who would only be using the computer for word processing and web browsing. Nothing too special is needed.

He had a few things he wanted though,

at least a 15.5 inch screen
built in wifi


that's it.

I was thinking maybe this http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=6325078&CatId=3985 ?

I only know intel CPU's so I am not sure about how solid the AMD one is. Any suggestions?
