Do these two cards have similar power consumptions?
Looking to upgrade my GPU, just hoping i'm not going to have to upgrade my PSU at the same time.

So, what is your current PSU? brand? model?

You should be fine upgrading to a 5850 as long as you have 2 12v rails that have at least 16a. A decent 500W should suffice as long as you don't overclock too much, or have too may case fans.

The 5850 uses about as much power. As long as you have a good quality PSU with enough amps you should be fine. If you were stressing it with your 4870, then it may have a shorter life than you think regardless if you stay with your current card or drop in the 5850.

\^_^/ yay for a 5870. As you can tell from my sig I'm powering mine with a FSP 500W Blue Storm II. Happy gaming.
