I am using DriverFusion ,doesnt have to be Premium version,in safe mode,tab is driver family,check AMD drivers,delete restart,and clean-install your downloaded drivers,never had any issues,Nvidia user here,give it a shot!

Video card most likely come with the driver software and yes AMD Catalyst is control panel for Video card and includes the drivers, but best just download newest because card may not have the newest drivers, get it here as said, whatever system is 32bit windows or 64bit.
Download Drivers
True never buy exact wattage you need for a PSU as other devices also draw power from it, said before matters how many other hardware devices.

Update: sapphiretech.com website only offers to download the: AMD Catalyst Software Suite - no drivers (as far as I can see)


SAPPHIRE TechnologyB0A096A09D87&tag=download&lang=eng

That is the driver. It includes the Catalyst Control Centre as well as the drivers (GPU and HDMI audio). Just make sure to run a custom install and uncheck the gaming app (can csaue problems).

Also the download from Sapphire will be identical to any available straight from AMD.

Update and Closure (26:06:2015):

Due to a Post strike the SAPPHIRE Radeon HD 7750 1GB has only just arrived by my son, but he has installed it, ran the AMD Catalyst Software Suite, and says everything is fine.

He is really very happy with the gaming improvement.

My deepest thanks to all for the help and advice – you have all been a tremendous help and support in this – Thanks so much
