Hi guys. I want to build a gaming PC soon and I want to spend just a bit less right now and spend more later so I was thinking of buying a single 7870 right now and then later buying another to Crossfire it. I wanted to know what the wattage of my PSU should be. Just to play it safe, I'm planning on getting a Rosewill Hive 750W on Newegg. If you need to know my Motherboard I plan it to be a GIGABYTE GA990FX-UD3 AM3+ with a AMD 6300.
Thanks for any feedback. It's appreciated.
