SLI Vs Crossfire

[Gregster]

This was quite interesting for me as an SLI user. I was quite surprised to see the differences swinging in favour of one or the other. I understand that both have a fair bit of overclocking head room also. I consider these cards quite evenly matched but this so isn't the case with some games.

That graph's probably changed now since the latest beta driver has given upto 25% improvment in some games using 7970 CF.

These results vary wildly from driver set to driver set. I know skyrim and batman AA have had horrible scaling on crossfire with the 12.3/12.4 drivers when most reviews were donr on the 7970 cards. Skyrim scaling is definately fixed now, not sure about batman. I assume the same has happened with the nvidia drivers over the past few months as the SLI profiles improve.
