By the way, from what I've seen Crafty will get more kN/s than Fritz will. Crafty has better support for HT, too. The only way you will come close to 3 million is by using an AMD system. Those don't need HT and are fast already. Crafty gets 1.3 million nodes/sec on a P4-3.06GHz with HT, 1.8x speedup and you've got just over 2.3 million nodes/sec, just as Hyatt has shown us here with his 2.8's. Now, you don't get to use HT (well, it's not useful yet) in Deep Fritz. Take my CPU for example. I get about 1.6 million nodes/sec in crafty's benchmark. 1.6 million * 1.7 speedup = 2.72 million nodes/sec. This will also be quick for Deep Fritz, too. If you want speed and don't mind pushing your chips a little (only 10% overlock, not much at all) you'll have the fastest box. Considering the motherboard will be $150 and each chip is less than $100 thats a pretty good deal. ~$1000 for a system that gets 2.72 million nodes/sec without any HT help OR $4000-5000 for a system that gets 2.31 million and has to support HT. I don't know about you but the decision is pretty clear to me..
