Last week Nvidia launched the new GTX 980Ti model of Graphics Processor Unit which is the newcomer in a long list of GPUs released by Nvidia so far.
The latest GTX 980Ti is the closest you can get to the top of the range TITAN series of GPUs which have the highest performance specifications in the Nvidia product line. So if you are one of those that cannot or would not want to shell out a lot for a GPU, specifically the TITAN then 980Ti is the next best GPU.
This new card is 6GB strong and can play video upto 4K resolution. Also its SLI ready which means you can put 2-3 of these in your rig and have a real powerful GPU performance, but that depends user to user basis.
