Penryn is a town in the Cornwall district of England, lying on the Penryn river. The clues that helped me with this are that a while back I heard that Intel was naming these classes under bodies of water.
Now back to technology. Rumor has it that DX10.1 is going to be released soon, with the added feature of tesselation. Some claim that this is when the 2900XTs will shine because they were designed for this or some such nonsense. I'm not hating on either company. Personally I'm going with a Crossfire setup of the 1GB 2900XT (will wait till October though, just in case) although if there's a massive uproar over the G92 being the new king of the hill, then I'm sure I can do with one GPU.
We all remember that AMD is working on Fusion, right? The integration of a CPU and GPU into one motherboard, or something similar? That would be a MASSIVE change in the industry, because then the days of 1 kW PSUs is gone.
Anyways, I'll get back to research on parts.
