I stuck a new graphics card (Nothing fancy, a Sapphire with 256Mb DDR3) up the user port of my less than one year old PC yesterday. This also forced me to replace the power supply. Well, I'm done rewiring and setting up now, and dear me what a difference.
When I'm buying a computer I don't go for the fanciest new stuff: I buy medium range and pay a lot of attention to the potential for upgrading... Then, as the prices come down, I keep adding stuff until I hit the roof so to speak. Anyway, this got me thinking:
What are you lot putting into your machines to prolong their life spans?
