Benchmark Conclusion

This is not a thorough test, but you can see what you can get with this old machine. With multiple searchers enabled, it can handle 6 search requests relatively easy.

Not So Official Hardware Guide

I had my hands on a Xeon 5160 3GHz, 4G memory, Scsi 100G hard drives with Dell PERC 5/i integrated RAID controller, for indexing. DBSight's multi-threaded indexing scales amazingly fast on multi-core processors. Indexing 2.2 million records, 1.45G data takes about 25 minutes. The memory is not fully used.

However, Intel's Core 2 series can get faster: http://www.gamepc.com/labs/view_content.asp?id=5160vs6800&page=12 This is because Xeon's memory is slower: http://www.gamepc.com/labs/view_content.asp?id=5160vs6800&page=7

DBSight's indexing also needs faster memory. So I guess an Intel Core 2 E6700 could be your best choice.
