Well there it is. Here come the questions.
I plan on overclocking my CPU to about 4.5 GHz while also SLI'ing two GTX 670's. The question I have is will the cooling systems that are already in the tower be enough? Or will I have to add more fans to keep everything at an optimal operating temp? Colder is better as they say but I also am trying to not spend more than I have to.
The second piece of info is that I am not purchasing all of this at once. Right now, being this next week, I will be purchasing the CPU, SSD, Mobo, and RAM. What I want to know here is will I be able to run all this off the 450W PSU I have right now? Last question. I know that this rig is gonna rock almost any game once I finish the build, but can any of you guys give me an estimate of when I'll have to upgrade in the future?
The fans in the tower/on the components should satisfactorily keep them cool, but if you want to be sure you could perhaps switch out your graphics cards for Gigabytes Windforce, which has three fans. You would lose EVGAs overclock, but if you're already planning on overclocking your CPU, then you could easily do the GPU also. As long as you don't have the GPUs yet, a 450 watt should be more than sufficient for powering the CPU, SSD, Mobo, and ram, depending on the quality of the supply. As for future proofing, I probably wouldn't be worried about upgrading for at least 3-4 years. This is quite a system.
