I have a friend who does all kinds of nice thing for my kids and family and in return I would like to upgrade his processor for him he currently has a AM2 4000x2 cpu . He runs xp and has 4 gb of ram in the system. The mother board I used was a business type gigabyte motherboard with ati graphics and if I remember correctly is limited to the 95 watts cpus. He mainly surfs the web and muti tasks a lot, burns DVD's etc.. but doesn't game. Whats a decent, less than 100.00, cpu upgrade where he will see a difference in performance. Give me some impute . I have some ideas myself, but wanted to see what you think. here are the two I'm looking at http://www.newegg.com/Product/Product.aspx?Item=N82E16819103678 http://www.newegg.com/Product/Product.aspx?Item=N82E16819103687 I'm assuming this has a ddr2 controller as well. Hes doesn't use many multi threaded apps.
