Well... After using it for a short while I started to smell something. My PSU started to overheat. I had to remove the card and put in my old one. So, my PSU is weak and I need a new one. Does anyone know of a PSU that would be powerful enough for this video card but can fit in my case? It's the case of an Acer Aspire T671.
EDIT: Also, I have an additional problem with my ATi Radeon HD 6670, which is the card I am upgrading from. When I have the GPU clock at the default 800 MHz, and begin playing a game, the drivers crash and recover a few seconds later. It works fine at 700 MHz, but I get less FPS. I use the 12.10 drivers, which are the most recent (10/22/2012).
