Hi, I think that my MOBO can support this processor, but I just wanted to check. I currently have a Intel Core 2 Duo E660 2.4GHz, with 2GB DDR2 533MHz RAM (2x1GB). My MOBO is an ASUS P5N-E SLI. (1) I want to upgrade to an Intel Core 2 Extreme QX6700 2.66GHz Quad Core CPU. According to the ASUS website, my computer can support Quad core. " - Support Intel® next generation 45nm Multi-core CPU - Intel® Quad-Core " (2) I also wondered how much is the maximum RAM my MOBO can support (can I put in 2GB sticks in or just 4x1GB). " - Dual-channel DDR2 800/667/533 " All help greatly appriciated in question #1 or #2.
