That makes a lot of sense, thanks so much, I'll post a second draft in a few days and would love some addition feedback then if you could. Thanks so much for your help already, you've all been great!Gordo74 said:That is still definitely overkill. Over the past few years, hardware makers are working hard to get their components to produce LESS power. Anything nowadays that will power a GTX 580 will be good enough for an upgrade in the future.
As far as the 750w number, that may be for a dual processor, server board with many multiple components that your system will never see. I stick to my recommendation, a good 650w will be fine.
