ATI 5870 + Crossfire Questions

[Shuggy101]

Hi guys

I bought my computer around a year ago from overclockers, I currently have a ATI 5750. I am looking to upgrade to a 5870, my questions are.

1.Will a 650W PSU (Corsair) be enough for a 5870? if so how about two 5870s(Crossfire)?

2.With Crossfire do you plug your monitor into one card? or do you need some kind of attatchment?

Thanks

Shaun

Plug it into the top card (not that it matters). The Corsair should run the 2 cards ok. What else you got running?

PSU will be fine.
