Hi there. I have 2 EVGA 690 GTX video cards in SLI. Is it worth upgrading now? I am i better off waiting for the next generation of NVIDIA cards to come to the market?
Now this is an interesting question - as not many people I've talked to have NVIDIA GeForce GTX 690 cards in SLI - but they're still a kick ass combo, even today.
My suggestion would be to wait. NVIDIA, as I'm sure you know, has next-gen GPUs on the way in the form of the Pascal architecture. They will feature HBM2, with some cards poised to use GDDR5X (a faster version of GDDR5 that's on today's cards), the Pascal architecture, and shrunken down onto the 14/16nm node.
This will provide a huge increase in performance - just from the node shrink, not to mention the 1TB/sec of available memory bandwidth courtesy of HBM2. This is without mentioning the huge architectural advances that Pascal will deliver over Fermi and Pascal. It's quite the perfect storm for NVIDIA in 2016... which is only going to mean great things for consumers.
So in finishing - wait, please... just wait. You're going to love what next-gen GPUs deliver.
