I wasn't sure of which section to put this in because its a mixture of two things... Around last year i got a Radeon HD 5770, a new CPU (AMD Athlon X2 245) and a new PSU (An Antec EA 500w, which was below the 5770's required +12 volt rail) and something went wrong. In the Sims 3 I noticed graphics artifacts, such as the water turning white instead of blue and sharp edges showing up even though AA was turned on. I'm hoping that that there's something wrong with my CPU and not my graphics card but then again i used it for a while with the power supply i bought and it was below the requirements. And the reason i'm asking this is because i've been told by a computer technician that CPU's help with graphics in games.
