who gives a, one game, that doesn't need high performance.
also as for the [h] benchmarks, i'd like to see it with AA on, at max on a setup like that, you'd find that the max would be much lower on both the systems, and that the average would be MUCH closer on a quad and dual core. all benchmarks can be run at any settings you want to show whatever you want. you can interpret the answers and show the results in any way you want to make them say what you want.
its all silly, for 99% of people the Q6600 might be great value, but , personally, considering power consumption it will be expensive to run and barely get used for 99.9% of the time you have your computer turned on. i think for most people, the penryn or phenom is the first quad core they should be getting, smaller process, less power, same power used as a current dual core. theres just no need for a quad now using twice the power. a penryn at the same cost will run cooler, cost less to run, and there might even be 2-3 more games that can utilise quad core.
remember, just as dual core when it first came out lots of games would put the "dual core enabled" advertising on because you advertise ANYTHING thats an advantage over the competition. for instance, when source moves over to multicore, hl2 will be able to run on a multicore, will make no difference whatsoever to how it plays. 50% of a fast single core, or 15% of 4 separate cores is still the same amount of work. everyone wants to offer the same features, however useless, as the competition.
