The ram won't make a huge difference either way. It would if your chess program started swapping, but if it was swapping, processor speed wouldn't make any difference. A $1800 AthlonMP 2400 system can almost tie the dual-Xeon 2.8 GHz. It would be more cost-effective just to build a NUMA system out of 4 such nodes. You'd probably get about the same speed-up. -Matt
