Looks are fine, but performance is what matters.
It is essentially the same motherboard, so read the other review if you're looking for tables of FSB settings etc. The cosmetic changes are the most obvious - these are unlikely to offer any real benefit. The platinum heatsink may be more thermally efficient, but I don't think it's going to be a major difference to the Gold model, or even the more conventional green sink found on the plain Pro board. The 2 ISA slots from the Pro are gone, having been replaced with another PCI slot for a total of 6. Interestingly, the IRDA header has moved from near the PCI slots to near the floppy connector.
