Self build – Overclockers and Scan.
Have been doing so for 10-12 years. Second PC purchase, circa 2000, was utter shite – motherboard and video card didn’t like each other, performance was poor and kept having lines across the display. Tech support tried to fix it, even came out to install another crappy m/b.
In the end I told them to bog off and rebuilt the system around the m/b and cpu that I wanted.
Can be nerve wracking at times. I normally have an old HD in the machine – mostly used for storage, but with a second bootable OS. at least I have a way back in if the system falls over.
