I'm thinking about getting another 3870 ati gpu. Do I still need to get an dvi,dms cable to connect them both or that is what the crossfire ribbons are for. I am still confuse about this because I am reading about crossfire and people are talking about the very old gpu and never one that tell me how to do crossfire with the new cards. So can you give me some link for a website or tell me how to connect my crossfire into my computer.

Thx for reading this message. P.S I am very bad at english lol.

I would get a better card. A 4850x2 would completely outperform 2 3870's.

This is true, but it would also be more expensive than getting one more 3870
