i have flashed hd4890 installed in mp1,1. have original x1900 xt sitting somewhere collecting dust. drawback can't enjoy second screen in osx started miss much. plan try new setup i'm not sure few things, knows better on subject please enlighten me. here goes:
let's put x1900 xt in. connect second monitor on dvi port (it's connected through hdmi on hd4890). crossfire cards together.
1) understand crossfire doesn't work on osx. shouldn't prevent cards used separately normal though, it?
2) in windows, crossfire work (given install needed drivers) or need setup cables differently (e.g sli y-shaped cables)?
3) in osx, x1900 xt have significant difference vs hd4890 on video performance? because used movies. never got 'hd' thing anyway, x1900 supports higher res 'full hd' , it's doable through dvi cable, if want video , not sound. both cards have 'avivo' technology i'm not sure it's supposedly meant hd video.
so, thoughts on this?
how many power cables need?
assume 4890 uses 2 power cables, how many power cables x1900xt need?
