Hi, well I bought a new computer about 2 months ago and I didn't like the graphics card that came with the computer. The video card is a GeForce 6150SE and I hate the way it plays BF2142, Guildwars, and Counterstrike:Source. So I have decided to get the EVGA e-GeForce 8600 GT 256MB PCI-Express. But my friend has told me that I need a better power supply and I dont know a whole lot about computers so this is where I need help from anyone that knows something about this stuff. If anyone can help me find a good power supply that will last for a fair amount of time, it will be greatly appreciated. By the way I live in Canada so if you can find my prices in CDN dollars that woul help a lot.
