[TimRayder]

Hi, I'm Crossfiring a XFX 6790 with a HIS 6790 and I need to know if my power supply can handle it.


My power supply is a: http://www.ncix.com/detail/ocz-modxstream-780w-atx-v2-2-1e-23962.htm

My processor is a: http://www.newegg.com/Product/Product.aspx?Item=9SIA63920A0121&cm_re=amd_athlon_II_x3_445-_-9SIA63920A0121-_-Product

But I'm upgrading my processor to a: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=9494388&CatId=7339

Will this setup work?
