E8400 upgrade help
I sent a request to RMA my Evga 680i mobo because it is the TR version and I heard that Evga can replace it with an A1/T1. I am looking to get an E8400 for its OC popularity. I have a Tagan 580W PSU and Corsair XMS 2GB DDR800. Eventually I plan on adding another 8800GTX for SLI. I know that a new PSU is in order. My question is if i am going to OC the E8400 to about 3.6-4Ghz, is my ram good enough? Also, what PSU would be sufficient for this OC and SLI 8800GTX. Any help would be appreciated. Thanks.
