It`s all a bit of cat`n`mouse afaic. Intel have done graphics for a long time, but not ones that would perhaps challenge the front runners of nVidia/ATI.
It also appears very silly, from the outside looking in, that there have been mobos that will do crossfire, won`t do SLI, won`t do crossfire, will do SLI and maybe some boards that do neither.
The community tried their thing with `hacked` sli drivers and the like, showing that, especially with support, boards available were `capable` of doing the things they were acclaimed not. Claims obviously meaning "we don`t want them to do...". Then the process gets crypted as a result.
I`m pretty sure all parties involved have their own faults in terms of co-operation, but it hasn`t seemed to have helped the gamer especially. SLI, in theory, is meant to be an awe-ground breaking performance booster - and in reality the majority use it as a benchmarker - only to fall back to one card due to stability or compatablity.
1 thing I would acknowledge is that anything Intel releases as a dual card graphics option is going to be pretty solid in the driver department. But I would only question, as with the regular SLI debate, will 2 of their cards work better than an equally priced single nVidia ? Early stages, probably not, but I have no doubt they`ll get better - and have a solid platform to work off.
Never thought this to-and-fro`ing and variants of mobo standards was good for the industry tho. I`d much prefer a standard of 2 pcie slot mobo and be able to stick in 2 cards of my choosing. I think it holds the tech back, imo.
