But I am a stock broker and I also use the Dual Xeons for business applications beyond chess. Yes the AMD systems are less expensive but it has been my experience that you tend to get what you pay for. For Business applications and engineering applications the Xeon will dust any AMD on the market. AMD is great for gaming! In single cpu systems they do seem to outperform the p4 on a elo per MHz basis but dual systems are a whole different story and there has been little testing on the chessbase server with newer high-end xeon systems because for most such tests are cost-prohibited. I won't knock the Xeon system until I have it in hand and have the opportunity to test it along with the new E7505 Chipset. Once the system is in hand I will run DeepFritzMark tests with hyperthreading disabled and then enabled at different hash settings and post the results here. My 2.8 GHz P4 with a 64MB hash has a fritzmark of 1319 and is in the ballpark of 1038kNs (Dell Dimension 8200, 533MHz FSB, 512MB PC800 RDRAM). I have seen many exagerated fritzmark claims here in some of the postings. I expect in the ballpark of 2500 kNs with Deep Fritz 7 on the Dual 3.06 Xeons perhaps a hair more if the hyperthreading works well with deep fritz 7. All I am saying is lets be fair and not judge the Xeon systems until I have had a chance to test the processors with the new E7505 chip set and the DDR RAM.
