As many of you know, The GTX 780 is rumored to be released on May 23rd. Good News, maybe; a couple web sites are saying that the GTX 780 will have 2 x 6-pin connectors. The GTX 780 will be so powerful, will 2 x 6 pin connectors be enough to power it? The newest rumor has it that the GTX 780 will only have 3GB of memory. Previous rumors had it at 5GB of memory. The 3GB of memory makes sense to me, that way video card manufacturers can make a 6GB GTX 680 as well as the 3GB card. Many web sites show the GTX 780 TDP to be 250W which is the same as the GTX Titan. 250W seems high to me. I used a number of sites to make the following chart. It compares the GTX Titan, GTX 780, GTX 770, and GTX 680.
