J&W truly surprised us by jumping straight into the X48 platform. And to be honest, the performance was extremely impressive. While it doesn't seem that way when you look at the scores, there are a few things to consider. First off, compared to P45, the X48 is the first gen 4 series chipset from which the P45 has since evolved. P45 contains the same DDR2 and DDR3 memory controllers, but with a few features disabled. So, X48 and P45 on the memory and CPU fronts should perform identically, making X48 and DDR2 really a waste; only with DDR3 and XMP does it become attractive.
The second major thing is that X48 has a better Crossfire setup, allowing for CrossfireX where P45 doesn't. This is the big aim for the J&W board, aiming at high-end users wanting extreme performance and to do that you need a good board (which we think the J&W offering is) along with solid components like a Core 2 Quad or high-end 45nm Core 2 Duo and two GPUs to really take full advantage.
On the whole, the board impressed us. However, the lack of information on the box and complete absence of artwork really left us with a feeling of an OEM look with extreme performance. Maybe splash some more colour on the next line-up of packages J&W, this would be better.
