E8400 upgrade help

[Kemo]

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.

750psu would be more then enough. Heck I can run dual 8800gtx's and the rest of my system on a 620hx. I'd suggest upgrading your ram to 4gb: it's very cheap these days and you'll suffer from having sli and only 2gb of ram. Also vista 64 or xp 64 would be a good idea.

9 x 444 = 4.0ghz, most decent DDR2 800 should be able to pull off 900 Mhz.

3.6 would be possible ( 9 x 400), up to about 4Ghz should be relatively easy. All the DDR2 800 I've used would do at least 900 Mhz.

thanks for your help folks. My RMA request got approved so I'll be shipping my board out tomorrow. Any PSU in particular or just any 650-750w PSU will be good?
