hi i'm building a new pc i will get a http://www.amazon.com/gp/product/B003O8J12I/ref=gno_cart_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER i noticed that the 800w and 1000w is only $10 difference should i just get the 1000w <edit: my build wont even use 600w >
You could get a lower watt, platinum rated power supply at this price point.
If you don't need the watts, the use your cash to buy quality.
I personally use a rosewill fortress 750w 80 plus platinum and I love it. If I were you, I would get that.
What are you powering, and what is your budget? I'm already going to tell you not to get the 1kW PSU, though.
Bought a 1500W PSU once (it was on offer) and i can safely say it was a waste, not only was it far too over spec for the 2x295GTX's but cos it was never really pushed its efficiency was rubbish.
