When I built my PC over a year ago, I went to Priceline.com and researched the cheapest price for the parts (which I researched on tech websites such as AnandTech) figuring in the cost of shipping. I used newegg, powerstartpc, gogocity, upgradeplanet, cardcooler, & z-buy. After my initial purchase, I returned to newegg to purchase my video card. Their website was the most pleasant to shop at. Hope this helps some.
