I have the ms-7241 motherboard with an E6600.. I would like to upgrade to quad core cpu like a xeon. Though is this motherboard compatible with core 2 extreme and xeon?
Sadly it is not worth investing into anything better as the best CPU is Core 2 Duo E6700 which is at best only 5 to 10% better than your current CPU.
I would look into used motherboard which supports quad CPU.
