Holy shit dude, that guy fucked you over big time for 2k...
He managed to get u a shitty gpu, so that he could spend more on other parts... yet they are all junk for a 2k budget.
Sounds like he cleared out his unsold inventory.
Could've got k version of cpu,
Z97 board
Reliable psu,
CAS 9 rams at least
Etc.
Never go to that dude again lol
Before you upgrade though, have u updated Ur drivers to latest?
With 400-500 budget, go for the 970
