I am going to retire my main rig and break it down, then transfer my dual GTX 470 to my new rig that has dual Xeon, and add in 2 more video cards GTX 580. 470 already have water blocks installed. The new rig with EVGA SR-2 will have water blocks on chipsets and both Xeon CPU.
I am trying to find out about how much heat both GTX 470 and GTX 580 in watts so I can see if I need to get new radiator or not. I tried using Google but it's not helping me with useless information like minimum 550w psu, etc. I don't want PSU (1500w is enough, tyvm) I just want the TDP. Do any of you have TDP info?
