For 200 bucks I would definitely buy something like this: http://www.motherboards.org/reviews/hardware/1836_1.htmlOf course choosing the company is a matter of taste. Keep in mind that your PSU is the absolute minimum required for this setup. All cards from GF 2xx line requires 500W PSU or better, ATI cards are even more power hungry. 480W PSU should handle it flawlessly but I don't recall Orion brand. It should be high quality.
