What is better

[wade3590]

right now I am running 2 4870 in CF,

considering buying a 285.

which is better?

4870 CF.

Even if you're playing a game that has absolutely no support for CF and only uses a single 4870, the performance increase you'd get from having a single 285 would not be anywhere near enough to make the purchase worthwhile. Unless every single game you play hates CF, and you have a couple of commas in your bank account, you're better off sticking with what you have.
