Anyone know anything about this GPU?

I could not find any reviews for this card just places to purchase it. Help is appreciated :)

None of those links have anything to do with the 

VisionTek Radeon HD 7790 Video Card - 1GB

They are 7790s yes but they are different models and are all OC'ed. I want to know how the VisionTek Radeon HD 7790 Video Card - 1GB performs.

There is a Sapphire Radeon HD 7850 1GB Video Card for $145

Much better perfomance...outherwise there is the Asus Radeon HD 7790 1GB $125

and the Sapphire Radeon HD 7790 1GB $130

Thanks for the help, getting a 7790 for my uncle's PC for gaming but I don't need to play games on super max settings. Just for when I house sit for him which is often.
