I want to sell my gtx 960 and buy used GTX 970 for 200euros.
The Asus gtx970 is mini and will fit my case but i am afraid that my psu will not be able to handle.

My psu is Antec VP450P its real power but the max load on +12v1/2 is 360W.
I dont have 8pin conector and i will use converter molex.
-Should i stick with my GTX 960 2GB and buy ssd (240GB) or get the 970?
-How much long will 2GB vram be enough to run games?
Thx
