I currently planning to upgrade my 5670 to a more powerful card around 150-200 bucks. I was wondering if i should upgrade my 460w power supply for my new card as well. My cpu is a 1045t if that makes a difference.
It depends on what you finally decide on for a new card. And it also depends on what else the PSU is powering. Here is a PSU calculator you can use once you settle on a card. http://www.thermaltake.outervision.com/
