Ok so currently I am using a MSI GTX 780 TwinFrozr otherwise knows as the "Gaming Edition." I'm using a 1200p monitor and the GPU does amazingly for this resolution. However in my neverending quest to create the best and perfectly balanced personal computer I will soon be upgrading that monitor to either a 1440p display or possibly a 4K but most likely a 1440p. Right now I have the opportunity to put in another $50 and "trade-up" to the MSI Lightning Edition GTX 780 which is known for its ability to overclock to ~1400mhz, getting better than GTX 780 ti performance, or so I am told. Otherwise I can throw down a couple hundred and bite the bullet to grab the GTX 780 ti and if anything ride that card out until the cows come home (or until I am thrust into 4K territory in which case I will probably get a second GTX 780 ti.) So I am just looking for opinions. If 1440p is my most likely next resolution is the GPU I have now good enough to get 60fps in most games? If not and it is between the Lightning 780 or the 780 ti which one would give me better performance for that screen? Also if I do go 4K can I do so with any single GPU setup or will I have to go SLI and if so is there any reason why two GTX 780's wouldn't be enough power? I want to make sure I am in the best position for the next couple years with the changes coming in resolution. Or should I just wait until the GTX800's come out and see what is going on with G-sync? Its a tough one and I thank you for the input.
