I don't know if you see Chess as a game or application...but it's still a boardgame..and they are just the right way to go with these multi core cpu's!!
Many years we have wait for them.
How more cores i see..how more the chess engine like it...from the E6600 to Q6600 and now I7 core 920 i get millions and millions more positions in one second!
And it will comes better when we have the cluster version from these chess engines,because then we can connect different computers to each other and use all
these cores from these connected computers...then it will come interesting!!
When the games comes multi core then is chess already step further...Cluster!
