I have been googling like no one's business. Maybe I just don't know what to google, but I haven't gotten very informative results. So here's my question.
I have
AMD Athlon 64 X2 4200+ (windsor), AM2 socket, 90nm - processor (http://www.newegg.com/Product/Product.aspx?Item=N82E16819103747
Asus NODUSM3 - motherboard
nVidia nForce 410 - chipset
Can I upgrade to some type of Phenom II? (something on this list link http://www.newegg.com/Product/Produ...&cm_mmc=KNC-GoogleAdwords-_-AMDCPU-_-NA-_-NA).

I have read multiple time that AM3 processors will work in AM2 sockets, but I couldn't find out if the whole 45nm and 90nm difference matters.
