I have a Sapphire Toxic 4870 and was wondering if it would be compatible with another 4870 card that isn't exactly identical? Sapphire makes several different type's of 4870's and I was just wondering if other 4870's would work as well.

Sapphire 4870 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Sapphire Toxic edition 4870 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and theres actually a couple other 4870's made my Sapphire so I am a little confused as to why they have so many that appear to be the same card for the most part?

yes it will work with the other 4870. the diffrence it the Toxic has a higher core clock speed(780mhz) as well and higher mem speed(1000mhz) compaired to the vapor x (750clock, 900mem). What will happen is the faster 4870 i.e the toxic will slow its self down to match the slower card i.e the Vapor x. I have the vapor x crossfired with the diamond 4870 and it works fine. Just make sure they have the same amount of memory, i know the vapor x makes a 1 gig and a 2 gig version.

So basically if I get another card my best bet would be to get another Toxic 4870? Not worth going to a 4890 to crossfire correct?
