Tyco2000 :
When do you think the Gtx 980 will come out and at what cost?
They're already out, mate. Have been for a while.
If you mean the 980ti, they're probably going to be expensive and not necessarily worth it.
What resolution / refresh rate are you playing at? If it's the typical 1080p, 60Hz, there's not much reason to go beyond a 970.
