11-Way P45 Motherboard Shootout : Introduction

Introduction
When Intel released its mainstream P45 Express chipset, the biggest news was that it supported PCI Express 2.0. Formerly available from Intel only on high-end X38 and X48 motherboards, many of us still failed to understand the significance of this bandwidth-doubling technology to current-generation hardware. After all, the first-generation x16 slots found on P35 Express motherboards are still fast enough for any graphics card, so why bother updating?
In order to truly understand how important PCI Express 2.0 is to the (upper) mainstream gaming market, one has to consider the P45 Express northbridge’s other key feature: its ability to split those sixteen lanes into two x8 pathways.
The ability to run two PCI Express graphics cards in x8 mode hasn’t been available from Intel since the days of its 975X chipset. Dual-graphics P965 and P35 motherboards usually relied on x4 pathways for the second slot, starving the second card with a lowly 2 GB/s transfer rate. By allowing its 16 PCI Express pathways to be divided into two x8-mode slots, the P45 Express can now deliver the same 8 GB/s bandwidth to two graphics cards that its P35 predecessor could deliver to only one.
Other updates to the P45 Express technology, such as the ability to support a total of 16GB RAM rather than the 8GB of the P35 Express, are far less significant to the majority of its mainstream/performance market. In fact, those who would never even consider using Crossfire technology might prefer to save some money by purchasing a less-expensive P35 motherboard, as implied in our earlier P45 Express technology overview
Given that the P45 Express’ major features target gaming enthusiasts, it comes as no surprise that many manufacturers have chosen this mainstream part as the basis for reduced-cost, high-end products. Others have chosen to use only a minimum number of high-end features to bring added value to the budget/performance market. Today’s eleven motherboards represent that range of products bound by these philosophies.

Wait, i think i missed the conclusion... what was the conclusion.....or am i just silly !?
Great review any who, i have been waiting for one of these. I would say go for the P5Q Deluxe!!!!!!!!11
the old E6xx CPU is not good enough to explore the FSB of the new P45 chipset. i seen better review then this in term of hardware. there should be at least a dual core 45nm processor and a 45nm quad processor.
sigh....tom's been lazy with hardware update!
I assume it is a mistake that says the P45 platinum from MSI has an X48 chipset?
so waht about a decent conclusion something like, are these boarfds worth the extra cash over a P35 chipset variant, everything tells me they offer little incentive over the P35, thoughts anyone?
Hello?
Uhm .. 45nm!?
I agree, test with a better (new) CPU(s) 45nm Dual/Quad.
That would be really interesting. This probably means alot to someone that owns the E6xx series CPU which i doubt someone buy if they buy a P45 board.
Methinks Tom has a bit of biassed attitude favouring Asus tbh
