I can't say much beyond the reviews and B/M's for the SiS 648 board yet as it is due to arrive tomorrow according to FedEx...............

I was pretty impressed with it in the reviews and all, but, I just bought it because it was new and wanted to try it out............
As for the P4T533.............I will agree with the other guys that for the cost, DDR boards make more sense, but, what wasn't mentioned is the fact that there actually is 128mb or 256mb's of either PC3200 or PC4200 (whichever you pick and depedent upon where you buy) of RDRAM packaged with the P4T533 when you buy it! I got mine with 256mb's of PC4200 and then bought another 256mb's of Samsung for $147................not so bad............but still expensive!
If you do opt for the SiS 648..............be sure and wait until tomorrow and get the Samsung DDR-400 from NewEgg.......

Have fun and enjoy it!
