Tough crowd even on Christmas.
Polishing turd won't make it any more appealing. It's still a turd.
up to 250 MB of DDR400 SDRAM to the A1200 system memory!
The memory might be DDR400 SDRAM on the graphics card, but there is no way the amiga could access it even remotely the actual speed of DDR400 SDRAM (3.2 GB/s). In reality the memory speed is slower than the 70ns SIMM memory on your average accelerator.
Especially reading the memory is really slow. Graphics card memory was never meant to be used for reads and this is not optimized for it.
Elbox will spin this "DDR400 SDRAM" story for months no doubt.
