that would mean overclock Bclk, the system clock, which would invalidate p55 vs x58 results.
i've read to lower QPI clock when overclocking, but i never did, and still managed 215Mhz bclk on my Asus p55 deluxe board, 205Mhz stable (with lowered CPU clock, of course)
Another consideration for comparison is that the Core i7 960 3.2GHz is due Q4 2009 for $562--see Wikipedia > Nehalem > 45 nm processor architecture. Another site says it's due Oct.18.

The results are biased in how much better Bloomfield and Lynnfield peform when they both have DDR3, whereas P45 is only using DDR2.
Owning a Rampage Extreme, the results don't really tell me how much better i5/i7 really are than what I have now.
i just have the same results, so confuse:( why 8x8x have good as performance as 16x16x???:(:(:(
spec:
- P55: 8GB PC12800, HD4890 1GB CFX
- X58: 6GB PC12800, HD4890 1GB CFX
