In conclusion, I believe the Shuttle AS45GTR definitely cleared up all the criticism about the SiS 648 chipset. As I stated earlier, I was extremely disappointed with the P4S8X and its performance and must admit I blamed most of it on the chipset. But the AS45GTR definitely proved me wrong.
The stability on this motherboard was significantly better then that of the Asus. Running the test rig with this motherboard for about a week definitely assured me that it's 100% stable. And performance-wise, it isn't to shabby either. This motherboard isn't as fast as the Intel chipset we compared it to (i845E), but it still stuck with it and only lost by a few points most of the time. Perhaps we can see a performance boost with an updated BIOS?
The extra features make up a bit for the trailing performance. It comes with all the bells and whistles. Things like DDR 400 support, 6 channels sound, Serial ATA/RAID, IEEE 1394 Firewire support etc. This motherboard has all the features you will need (excluding LAN) and brings it to the table at a decent price. It is retailing at about US$121 on Price Watch; definitely a great price.
Tons of great features
No onboard LAN
