The Q9450 is due for official release on the 19th I think (in the UK at least, I expected the US to have it earlier *shrug*), so potentially another 2 weeks wait.....although if you keep a PC for 4 years, whats 2 weeks wait? :)
Hitting 4GHz is nice but there is very little that you would need that for. Games do not utilise that much power as most are GPU-bound, which leaves you are pure mathematical programs such as video encoders and [EMAIL PROTECTED] I have a water-cooled Q6600 that I have overclocked from between 3.2 and 3.7GHz since I have had it and in the vast majority of the work I do, the difference those extra 500MHz make are not noticable. With the new 45nm Yorkfield cores, its even less of an issue as they are supposedly 5-10% faster clock for clock over the previous 65nm cores. There has also been a lot of debate over the Yorkfield cores burning out rapidly when over-volted. The theory is that the 45nm process leaves them substantially more suscetible to burn-out and therefore keeping the voltage as close to stock as possible is advised for day-to-day use. It could be scare-mongering by overly-eager overclockers but I wouldn't chance any large voltage bumps on a yorkfield until they have been on shelves for a few weeks.

And there is no mention of the Q9450 on Anand's site or Tom's Hardware, which is really strange if the CPUs have been released (or are close to release). I'm also taking overclocking potential into mind here. I know that there are some on the list who shy away from it but I've overclocked every CPU I've had and always taken advantage of free CPU cycles. And I completely agree with the methodology and risks laid out here (which I am willing to take): http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3251&p=6 Many people are overclocking the E8400 to 4 Ghz with standard voltage and air cooling which is a definite bonus in its book. The Q6600 does alright and can get to 3 Ghz without too much trouble, but runs much hotter and sucks up a ton of power. The issue with the Q9450 is that it is multiplier locked at 8x, meaning the only way to overclock it is to bump up the bus speed which is a much harder prospect. Also keep in mind that the bus speed with a dualcore is essentially 1/2 the bus speed of a dual core. Thanks for the pointer on the mobo - you are definitely right on with that one.
