Regardless of the board when looking for 4.0GHz or higher with 45nm quad-core processors you will have to pony up that $1000.00. The facts are simple. With the added cache 450 FSB and above is going to be hit and miss at best. Play with the big boys and enjoy 4.0+ or spend cheap and stay 3.6 and below. With added cache and lower multipliers Intel has brought back the phrase "you get what you pay for."
