Alright, so this is a compability question regarding a 2006 MB and a 2008 CPU: I'm about to make a rather expensive deal, so before I do this, I need to know if there are any incompatible facts need to know of. The deal: I want to upgrade my motherboard with a new CPU. Current setup: CPU: AMD Athlon II 3700+ - 2219MHz FSB Motherboard: Asus A8N-E (Targa Edition) Memory: 2GbB DDR SDRAM (4*Siemens 512MbB ~350MHz) OC Videocard: 1GbB XFX (ATi) Radeon HD4550 Passive, 512MbB HyperX included Cooling: Cat-hair Soundcard/Speakers: Sweex SC015 7.1 / Pioneer SE-L40 from 1972 & Panasonic RX-CS780 Hard Disk(s): 2*7200rpm Hitachi, 300GbB, 1024GbB The newer CPU in question: AMD Athlon 64 X2 4800+ My old board has socket 939, and the newer CPU has socket 939 (this, I'm sure of). The current PSU has a total power-coefficient of 350W, but I have a 600W just laying around if I need to upgrade that part. Any thoughts? Like, "the motherboard's chipset doesn't support X2-CPU's" or anything like that would be greatly appreciated. And I do not want any comments about my PC being obsolete or "just buy a new PC instead." Edit: Ha, get this: the OEM manufacturer of the motherboard vs CPU stated that they made a mistake regarding the name back in 2006 - resulting in this Athlon 64 or Athlon II question. It is an Athlon 64 CPU, but it's called Athlon II by the manufacturer of the specific board vs. CPU configuration.
