I've never owned a Power Color card myself. The brand is actually always cheapest but I almost never see complaints from people who have bought their cards so there's no discernible reason to avoid it.
For the most part all the cards of a specific model are pretty much exactly the same. The main difference is the cooler and the price. Sometimes there will be a factory overclock but that isn't worth paying extra for as it's easy to OC yourself and you will almost always get better results.
This looks to be the same card with twice the memory(at your resolution the extra memory is entirely meaningless) and it has good reviews;http://www.newegg.com/Product/Product.aspx?Item=N82E16814131327
