Using the Shredder 7 (CB) GUI and Shredder 7.04 UCI engine I typically get about 70-80 kN/s in the opening/middlegame. In simpler endgames it may go over 100 kN/s, perhaps as high as 130 kN/s. Interestingly I can get much faster kN/s speeds for this engine if I use the Shredder Classic 6 GUI instead. I believe it has something to do with the hash. The hash table takes a long time to initialize (1-2 minutes) with the Shredder 7 (CB) GUI but is essentially instantaneous with the Shredder Classic 6 GUI. Perhaps that doesn't matter much with longer analyses of an hour or more(?). In most cases I'm using 160MB hash which experience has taught me works pretty well on my system, allowing normal multitasking of other apps at the same time. The GUI says I can use 190MB, which I do occasionally, but it slows down multitasking considerably. Like you I use infinite analysis mode. Also like you, I'm thinking about upgrading soon, and wonder which processor(s) would give me the most advantage...? WP
