TPM-Have an axe to grind with Sun?
Who the hell is 3leaf and why are you comparing them to Sun's T5440? If you had any backbone, you would have pointed out that the latest Sun T5440 absolutely blows away a majority of IBM's Power6 product line- and thats actually a headline grabber for your readers to click on.
Looking at the http://www.spec.org/jbb2005/results/jbb2005.html website, you will easily see that the T5440 4 x socket 1.6GHz server trounces anything that IBM can deliver up to an including the 8 x socket 4.7GHz Power 570.
Yes, thats right, a measly 1.6GHz UltraSPARC T2 Plus CPU is more than 2x faster than the Power6 which has almost 3x greater frequency. You can also point out that the T5440 results actually clobbered the Power 560, Power 550 and Power 520 systems.

As for T5440 pricing, its all available here: http://www.sun.com/T5440 and click on "Get It" for pricing of all configurations. The highest end config (4 x socket 1.6GHz) lists for $115,695 which is basically the system used for the Specjbb benchmark.
IBM pricing can be found here: http://www-03.ibm.com/systems/power/hardware/550/browse_aix.html
A 4 x socket 5GHz P6+ Power 550 lists for $115,204-roughly the same price as the T5440, however the T5440 trounces this system with over 2x the performance.
The 8 x socket Power 560 3.6GHz P6 lists for $139,751 located here: http://www-03.ibm.com/systems/power/hardware/560/browse_aix.html
Again, The T5440 outperforms this system by a wide margin and its atleast 20% less expensive.
So unless you are getting paid by IBM, you'd gain a little more respect comparing like for like (Sun vs IBM) systems instead of comparing apples to watermelons (Sun vs 3Leaf)
