Hexus spotted something interesting at Gigabyte's booth at Computex. The actual graphics cards weren't there yet but there were some placeholders with specifications of AMD's and NVIDIA's upcoming graphics cards.
The most interesting card is the GV-R395-512H, according to the placeholder this card features the Radeon HD 3950 GPU with 512MB GDDR3 and a 256-bit memory bus. I assume this could be a GPU that's a bit faster than the Radeon HD 3870 but slower than the Radeon HD 4850. Time will tell.
The Radeon HD 4850, GeForce GTX 280 and GeForce GTX 260 don't really hold any surprises, they just confirm what we already know.
