Tom's just came out with this report on the performance difference varying amounts of RAM have on an overclocked Intel Core i7 920 system. Short answer not much. The only real difference was in power consumption, with the 3Gig system, unsurprisingly, using 10-20% less. The other tests showed less than 1% difference.
The tests were run on Vista and hence may not be completely applicable to Linux, but still provide some interesting data. It would be interesting to see if Linux behaves differently, (hint, hint), also if using an AMD processor changes the results. I don't think it would but...
