Hey I'm chinese too .. but I was born in New Zealand so .. crappy chinese for me but good english .. .. but bad spelling lol .. anyways .. im not a big fan of pentium D's or celeron D's .. I'm sure for the same price u can get something with the core architechure .. least I know u can in NZ.. like
Intel Pentium E21x0, 1.6 or 1.8GHz, LGA775 or
Intel Core 2 Duo E4xxx, 1.8 or 2GHz, LGA775 or the
Intel Core 2 Duo E6xxx, 1.8 to like around 3ghz
I'd say go for something core arichitectured + great overclockers
