MSI's Big Bang motherboard equipped with Lucid's Hydra chip still won't be announced as it was apparently delayed, probably due to driver related problems that Lucid has to sort out before this motherboard is ready to be shipped to retail.
The motherboard got a new name as well during these few days and now we know that Big Bang is the name for series and not the actual motherboard as MSI already announced both the Big Bang Trinergy, a P55/NF200 equipped motherboard, and the Big Bang Fuzion which will be the one with Lucid's Hydra chip.
The motherboard will come sometimes in Q1 and if everything goes well, probably in the beginning of Q1. The Fuzion as MSI calls it now, gathered a lot of attention from the press and consumers due to the fact that it supports mixing of cards, even from various manufacturers. In the end this means that you don't have to throw your old graphics card which can be paired with a new one to give it a performance boost.
All we have to do know is hope that MSI will get this motherboard out as soon as possible.
