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.
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.
