well 939 processors will find you when you try to find them, they are quiet abundant. but i will suggest you to buy the new athlon x2 based on barcelona architecture. they are new and don't cost much, and they are way faster than you currently have. my freind has just bought one for a total of 20k. Specs: 2.8 GHz Dual Core, 4GHz Bus, 2GB RAM, ASUS motherboard /w SLI & Crossfire support, 300GB HDD, ATI Radeon HD 4770 1GB.
