First off, please do not turn this into get a GTX 670 board. I am getting a 7950 and was wondering who is currently consided to have the better 7950 card (MSI is out, I've never had a good experience with them). This will be my first Radeon card so I don't know much about the current state of their vendors.
Also, i tend to not OC myself. Any help would be greatly appreciated.
Sapphire tends to be the more popular choice with AMD/ATi side of things. I would go with either one of these 2. If you throw out msi I would get either sapphire or asus with AMD. And I would prefer the vapor-x over the asus card. Unless you had a red and black theme going then the ASUS card.
I have a 670 with a gigabyte windforce x3 and its pretty good. I don't care for there support so I left them out. When I called back in October Early November and asked if I were to RMA my card how long the turn around would be the lady replied 4 weeks that isn't customer support...
Sapphire's HD 7950 Vapor-X comes with a large dual-fan cooler that uses the company's famous vapor-chamber technology. On the Vapor-X you will also find a "Lethal Boost" button which switches to a second BIOS with higher clock speeds. With this BIOS, clocks are increased to 950 MHz GPU and 1250 MHz memory.It runs cooler then other 7950's overclocks like a beast!Hands down it's the best 7950.
The flex 3 is built with more display connections. The Vapor-X is the better cooler. XFX used to be amazing with customer service I'm unsure if they have came back up from there downfall. (There was a period where they went south on validating warranties.)
