I want to build a pc for as cheap as possible I have a 500watt power supply and a gtx 660 superclocked gpu
Question ... if you build it as cheap as possible, what do you expect it to do ? What monitor resolution ? And it would be good to know PSU model to determine whether its suitable for gaming type loads. A reference 660 (SC has same PCB as reference) will not perform well in today's games
here we see that a 780 was 1.67 times (100/60) as fast as a 660
here we see that a 970 was 1.14 times (95/83 as fast as a 780
here we see that a 1050 Ti was 0.72 times (100/139) as fast as a 90
1.67 x 1.14 x .72 means that the 1050 Ti is 1.37 times faster than the 660 or about as fast as a RX 460
Start here and go thru the pages one by one and see if you will be satisfied with the fps in the type of games you play at the resolutions you play at.

Witcher is 26 fps @ 1080p
GTAV is 33
RoTR is 30
BF4 is 33
COD:BO is 33
Far Cry Primal is 28
NVidia wants a 450 watt PSU so that should serve unless it's really low budget.
