It looks like AMD isn't waiting till the end of March or early April to 
launch its Radeon HD 7790 performance-segment graphics card. According 
to a 3DCenter.org report, the new graphics card will launch this week, 
either on Thursday or Friday, and that press-samples of the card have 
already shipped out. Based on the brand new 28 nm "Bonaire" silicon, the
 HD 7790 is expected to capture a price-point competitive to NVIDIA's 
GeForce GTX 650 Ti, around 135€. NVIDIA isn't sitting idle, and is 
planning a GTX 650 Ti refresh of its own.
