My 4-year old DELL XPS9100 is running a Radeon HD 5670. On the swap table in my building, someone left an EVGA Supernova 650 GS and an EVGA GeForce GTX 960. I don't do gaming, but I do graphics and occasional video editing.

Is it worth swapping my card for one of these? If so, for what reasons?

Thanks!
