You are reading the 1st link right.....it's a story from 4 months ago.
Now look at what i said and the link to the story from 2 days ago.....that says MSI is showing the card at Computex next week.
The Lightning was rumored to be dead never to go to retail but it will be introduced at Computex next week.
Why would MSI "introduce" a dead card next week ?
In addition to introducing an army of new motherboards, MSI will also showcase new graphics cards next week during COMPUTEX. These include the GTX 780 Lightning, GTX 780 Ti Lightning and the R9 290X Lightning. Also on display will be its line of "Gaming" and "Pro Series" cards.
The MSI Lightnings that were showcased in January were 3 slot cards which to my mind have little potential fr market success. The fact that they say "new graphics cards", implies..... well at least to me and assuming the author of that article is reasonably up on the state of technology in the market .... that this is a "new" Lightning, not the "old" Lightning that we saw back in January.
