im planning on adding a second hd6850 for crossfire to my build in the future but ill need a new psu. What i want to know is how many watts are enough for 2 hd6850s and maybe some room for overclocking my cpu.

i currently have:
AMD FX4100(plan on overclocking)
gigabyte radeon hd6850
g.skill 8gb 1600 ddr3 ram
WD caviar green 1tb

A decent branded 650W should be fine. make sure it has 4x PCIe power plugs

+1 to the Neo Eco as being sufficient...assuming that the HD6850 only requires one 6-pin PCIe power connector and that is the case for most stock clocked 6850s. Even Gigabyte's OCed Windforce HD 6850 - http://www.newegg.com/Product/Product.aspx?Item=N82E168... - only requires one 6-pin so the Neo Eco is good to go and good quality.
