Hi guys, I have a dell inspiron 531
and I want to buy a new graphics card for it.
I have been looking at the radeon HD 6570, which looks pretty good.
But I need to know if it's compatible with my machine.
If you want to know for sure connect a Kill a Watt to see how much power you are using under load. Most likely if you are running a 300 Watt power supply you don't have more than 200 watts of usability in it. I'm running a 5670 in my machine but I only push 170 watts under full gaming load because of how I built it. I'm also using a 380 watt 80% certified PSU, which makes a difference.
