[Jax.S]

the advantage of 4870x2 is that it takes only 2 slot and consumes less than a crossfire and a can over perf high resolution following a 2gb memory or perf level is the equivalent x2 has a crossfire.

[FAIRFAX]

For consolidation, sit a test of X-bit labs proves the opposite of what cyberpunkfw1983 a hd4870 consumers see less than a hd4870x2.

For the temperature and silence I believe that one hd4870x2 must do better than a hd4870 cf

The HD4870X2 has a potential of O / C relatively limited compared to the HD4870. So basically sit u put 2 HD4870 in crossfire, that thou O / C every 2 to catch, you atomised a HD4870 X2!
