$70 XFX Core PRO550W:http://www.newegg.com/Product/Product.aspx?Item=N82E168... (Not including $15 MIR). 550W is enough for a single 6950 no problem (AMD recommends on 500W or greater). If you are going to crossfire, moving up to the 750W should be more than enough, there is no need for the 850W version.
sorry but i asked in usd so that you didnt have to convert them to euros
and i wanted to order from abroad because prices here are 70-90 euros more
Anything else i should know before looking for a monitor?
