So in the coming months I want to start streaming on Twitch. I have done so in the past but stopped due to school and such. My current setup is

Processor: AMD 8350 4.0
GPU: Radeon HD7870 2gb ddr5
Mobo:Sabertooth 990fx r2.0
8GB RAM
Ample HD size etc etc

My question is, do you think if I upgraded to a 980Ti, this setup would be able to run WoW and stream at max settings? What about Fallout/Battlefield etc?

The current setup above is about 3 years old. The GPU has shown some signs of being on its last leg and I have been wanting to upgrade for a good while now. I feel that I have a good year at least on the CPU and Mobo, but if they would be limiting the setup if I made the 980Ti upgrade, then I would probably make the upgrade now to a better rig overall, either to a I7-5930 or 5960. Obviously that would be a large increase overall but if I can wait a year or so to do so for prices to drop and such, I would rather.

Thanks for the help!
