People keep talking about 'Custom Graphics Chips'. There were no 'Custom Graphics Chips'. That is just what we called GPUs back then. Now, every PC comes with them. Sometimes they have been integrated back into the same die, buy they are still there. Heck, the C64x is using ION graphics. That means that it is in fact a separate graphics chip. If Amiga had actual 'custom' graphics chips, each of us would have one that was made just for us, and that would truly suck. The proper way to describe the Amiga's graphics chips is to say that the Amiga had "proprietary graphics chips".
