If you are able to drive a little bit, you can go to Fry's Electronics in Concord:http://www.frys.com/template/isp/index/Frys/isp/Middle_Topics/H1%20Store%20Maps/concord/
They are a very big electronics store that sells both Palit and EVGA video cards. They will have good prices as well. If you are heading south to San Jose, there are other Fry's stores right off the freeway, listed on that store locator website. The one in Fremont is easy to get to.
I have researched both brands, and you could go with either one. The Palit has a custom cooler and the EVGA has the stock cooler, which is excellent.http://www.guru3d.com/article/palit-geforce-gtx-570-sonic-platinum-review/
