I am assuming thats prob one of the best crossfire options... but i know i got to get some HEAVY cooling done or else its going get blazing hot.

I am using BTCGUILD until deepbit fixes their shit.

Crossfire actually degrades mining performance.

Three 5870s will be exactly three times as profitable as one 5870.

He can just disable crossfire.

It depends on many factors... see the link in my sig for "should I buy or mine".  With that spreadsheet, you can calculate exactly how much profit you can expect from mining.

3x 5870s inside of one box will be more profitable than 3x (1x 5870 in one box) because the box itself has electricity overhead.
