I'm in a similar boat, except my card is still in the process of dying (still works, but lots of artifacts popping up). Lol
I'd quite happily buy a cheap, but better used GPU. But only one that is equally, or more energy efficient than my current one (otherwise I'd need a new PSU too), obviously better, and ideally can record using shadowplay or AMDs equivalent.
Basically a GTX 960 (2+GB) or better. Lol
My current GPU is an AMD HD 6870 1GB.
I live in England (Shropshire to be more precise).
