Nforce 790i ultra sli intel 755 socket. Found a working rig for 50 bucks on Craigslist and it hadn't ran since 2008.longt story short i cleaned it and it runs great. Problem is the cpu is only a pentium d 3.40ghz duo i think.wasnt exactly flying. MAIN QUESTION: i read it can take an intel core2 extreme X9770 as the most powerful CPUit can handle but prices are insane. Can it take an i7 or is the extreme 2 worth it or should I drop 250 on a decent new mobo i5 or something instead of the hassle/price. This mobo looks nice and prices made me question why so valuable.
