How well does the combination crossfire/SLI motherboards perform
I was looking at this post ( out of curiosity) http://www.hardwarecanucks.com/forum...if-needed.html
and noticed that the motherboard supports both Crossfire and SLI, how is this possible does the board have two chipsets? also I search very quickly through the reviews on Motherboards and haven't noticed any reviews on Boards that are able to do this. iof these mother boards to perform equally on either SLI or Cross fire I think that I just might start a brand new build. this is one of the things that has been holding me back on upgrading .

all P55 and X58 chipsets can run both CrossFire and SLI...check that, most can. some manufacturer's aren't licensing some boards to run SLI. all Intel chipsets up to this point have physically been able to run both...NVIDIA simply wouldn't license non-NVIDIA chipsets to run SLI previously, that is all. there is nothing special in these newer chipsets allowing both, they simply don't have instruction sets preventing it like previous ones. performance is going to be as good on any SLI or Crossfire chipset so it isn't like you are getting a castrated version. the ability to run SLI Crossfire all comes down to drivers, hence why some recently have shown hacked drivers allowing SLI on X48 chipsets...still not released but apparently do-able.

Wow I never new that. I guess I was holding off for know real reason then .

yup, just make sure the board supports both SLI and CF, i know forsure that one ASUS board didn't support SLI (they didn't want to pay the licensing fee as it is mid range) but i am not sure if there are others. be careful though, some companies may not fully advertise the ability to run both.

take EVGA for example, they don't heavily advertise their X58 or P55 lineup as Crossfire compatible, they push SLI. the simple reason is that they don't sell ATI cards, naturally they are going to want you to run SLI (NVIDIA cards they sell). it is in the specs but only a single line and that is it. heck the names of their boards have SLI right in it leaving some to believe you can't run Crossfire on them. so just do a check on the board you are interested in, but even if it isn't in plain site, it still might run both. you can always post up here with your selections to double check :thumb:
