@s{quotedtext} @s{quotedtext} GPUs suck at accessing main memory.

But they're very, very good at accessing on-board memory.  See, for example (from a couple of years ago)

@s{quotedtext} @s{quotedtext} I predict it'll take... mmm... 3 weeks after source code is released for the first faster-on-a-GPU solidcoin 2.0 closed-source miner to come out.  8 weeks until there's an open-source one available.

But my predictions are often wrong.
