Personally I prefer Asus. Gigabyte and MSI also fine. As for price I think it depends where you live. In my country leadtek and zotac is among the cheapest for nvidia brand. Never use zotac but did use leadtek before for my 660 SLI setup. They were cheap but when we talk about build quality only so-so. Had them for almost two years before I got my 960. initially I was thinking holding out until 'true' next gen gpu comes out but one of my 660 fan goes kaput. The other one seems on it's way out as well. My older 460 which also made by Asus fan still working fine even after two years plus.
