Hi Lukasz, I have five core2 and one i7 computers running at home. I prefer i7, though don't have exact measure.
The most important difference is the memory interface, ie, core2 uses a obsolete common bus (FSB) while i7 uses p2p connection with an internal (on chip) memory controller. Also, core2 uses DDR2 (obsolete) and i7 uses DDR3 memory modules. On overclocking, i7 performs better. i7 920 (cheapest model) runs at 3.6 GHz (C0 stepping; recent D0 is said at 4 GHz) while core2 Q9550 (middle range model) runs at 3.2 GHz, with a rather silent air cooling. If you have a benchmark program please send me. Ubuntu Linux or WIndows XP is fine. Ah, I don't prefer two sockets SMP computers since we will have hexa and octa core chips soon (next year? I don't remember).
