My Striker died and I don't even want to deal with it any more. I can't even get a good stable clock pass 3.0 GHz. Going to RMA it and put it on a different system. Make use of my E6600

I have no choice but just to stick with SLI(8800s gtx). Will it be worth it to go with Evga 780i? The price looks so good on Newegg. And which brand in that bracket has been known to be a great overclocker? Thanks.
