New rumors have emerged, and let me clear state rumors here that a 6GB version of the GeForce GTX 780 Ti is in the works. AIC Partners seem to be waiting on a green light from NVIDIA so that once the GTX Titan inventory clears up they can introduce 6GB parts. The stock of the GTX Titan is already in a somewhat slow trickle state because of the launch of the GTX 780 Ti.
We believe that one of the major reasons why no 6GB version has been released yet is so that people still have sufficient reason to buy the GTX Titan. According to our sources as soon as the GTX Titan Inventory Status clears up the 780 Ti 6GB Variant will start shipping.
Of course 6GB of VRam will allow the 780 Ti to utilize its full potential. We have seen that the Ti’s 3GB Memory causes some serious bottle-necking in some games while in 4k Resolution. We see that the Current Gaming trend is moving towards a 4k Standard and where resolution is concerned, the more VRam, the merrier. Not only that, but with the increased VRam, SLI configurations should gain more power. Ofcourse, professionals would gain the most benefit from the added memory, but for some reason or the other , the 780 Ti is just not as good with Compute as the Titan is. We expect that the GTX 780 Ti 6GB Edition should start shipping in a short time span.
