build
i5 2500k oc 4.3GHz about 1.3 vcore when OCed
7950 3GB stock
asrock z68 Extreme3 gen3
8GB ddr3 1600
Antec Bp 550w plus, modular


Now I went to http://extreme.outervision.com/PSUEngine and It recommended a PSU of 389W

However, When I was running GTA IV with Icenhancer 2.1 it seemed to be stuttering almost. I don't know if this is due to a small PSU or not. Do I need to get a larger PSU or no?

Thanks

as i say time and time again, a 550 watt PSU can handle any single graphics card system:
AMD Radeon HD 7950 3GB Graphics Card Review
with a sandy bridge-E system

if you are stuttering in a game, any game, that is a gpu problem.
a psu problem would be your system shuts down.

that would be related to the drivers but since i have not had an AMD gpu i could not tell you how to deal with the catalyst control center.

but i will suggest the generic uninstall the drivers, boot into safe mode and run driver sweeper to get rid of any remnants then re-install.
