Hey everyone, I am ordering 2 gtx 780's to put into 2-way SLI mode and I am wondering what kind of PSU I should go with. I was planning on going with a 1000W PSU since I am going to be overclocking them and it would be nice to have the headroom. Any thoughts? Also, I am running them with an Intel i7-3770 processor at 3.4 Ghz. Do I need to worry about a CPU bottleneck with this?
