I bought this system in 2007 and been playing on this ever since. I dont know how it does it but I was able to play most latest games on this PC. I played the Devil may Cry reboot last month. It even ran crysis 2 at decent settings with the blur and everything. My 1GB RAM gave out when I was playing Black ops 2 and I'm running the system with 2GB RAM for sometime. Things are not well after that. I know my system needs a graphic card, CPU and everything else update but right now for my own reasons I've decided to extend the life of this system. I have a Intel Core2Duo E4400 CPU. I want to upgrade to a better processor my board can support. Can some help me by finding out the maximum processor this board supports? Does it support Quad? I mean not the latest ones but 2007 - 2010 quads. I'm posting the stats I got from CPU-Z. Please let me know the maximum CPU I can upgrade to.
