I picked Combination. Before, I had a HD 7950 3GB, and that card had served me well over the last few years. I really did love how it OC'd. Then, when I upgraded my moitor from 1080 to 1440, The 7950 was beginning to struggle. I was initially going to get a second 7950, but I also noticed I was reaching the max 3GB of my 7950's vram on a few of the newer releases, especially with my new 1440p monitor. So, while I liked the performance increase from the GTX 970, I also was enticed by the extra 1 GB of vram that would give me some breathing space with the newer games....doh! Now, when I am playing at 1440p on games like Shadow of Mordor...The games does have noticeable stutters when using over 3580MB (which is pretty much all the time at this resolution). Had I known the truth, I probably would have kept my HD 7950 for another 6 months and got whatever AMD/Nvidia had to offer in 1H 2015.
