GeCube Radeon X800 PRO
The GeCube X800 PRO is based on, you guessed it, ATI's X800 PRO R420 variant. That means the following, compared to the range-topping X800 XT.| Product | Radeon X800 PRO - ATI R420 | Radeon X800 XT - ATI R420 |

XT with a bit less clock and a quad pipeline disabled, paired with 900MHz GDDR3 memory, is what defines the X800 PRO. Pitched as their current mid-range high-end entrant, if that makes sense, the X800 PRO is a £299 slice of GPU genius, to do battle against NVIDIA's 6800 GT.
To answer the question of new design or reference board on the previous page, here's the money shot.
At the current time of writing, there's only one or two manufacturers creating boards for ATI's AIB partners, so the scope for deviation from the reference design is slim. Not even the mighty ASUS does anything to X800 at the time of writing. Sporting GeCube's big-boobed lovely on their branding sticker, it's the only thing that lets you know who the vendor is. That's possibly no bad thing though.
The board uses Samsung's popular K4J55323QF GDDR3 DRAMs, rated to 1000MHz, 100MHz over the shipping clock.
Devoid of a Rage Theater ASIC or other means to get video captured, the GeCube X800 PRO sticks with VGA output, DVI output and TV-out as its connectivity options.
Unable to deviate from the reference board design, GeCube will have to focus on presentation and bundle to stand out from the crowd.
