Power supply and Graphics card question

I'm trying to find a graphics card to emulate games on Dolphin, but I am not sure if my power supply should be upgraded.

MoBo: Biostar A880G AM3 AMD 880G

Processor: AMD Athlon II X2 250
http://www.amazon.com/AMD-Athlon-3 [...] amp;sr=8-1

PowerSup: Antec 380 Watts Earth Power Supplies (EA380)

The two cards I'm looking at are these:

HIS Radeon HD 4670

Sapphire Radeon HD 5670

Can I use either one with my current power supply? As a side note, where could I find this information on my own? I did not even know where to look...

Thank you

  1. Your power supply is plenty for those types of cards.

    I would reccomend going with a 6670 instead.It's a more updated version than the older models.The 6670 is little more expensive but it has GDDR5 memory instead of GDDR3 as well as some performance improvements in several areas.

    MSI 6670 $100+$7 Shipping

  2. Awesome :D Thank you for the reply
