Just a useful link for those of you that are interested in computers. Tom's Hardware has an extremely handy page, which allows you to compare many of today's CPUs against each other in several different benchmarks. It saves trawling through excess pages of waffle, to get to decent benchmark results on the many reviews you'll find scattered around the web.
The link is here. I'll put it on the sidebar too for future reference - we used it to compared an 3800 X2 with a 3500 and were quite surprised at how well the 3500 still stands up against the 'newer' dual core offerings. Let me know if it's been of use to you!
