Which board? Yes there are some attractive choices these days. RAID or no RAID? The other question you may want to ask yourself is how important tech support & driver support is to you.
MSI is reported in these forums to be of little to no value tech support wise. Abit is said to be in extreme financial trouble and may not be in business by the end of the year. In fact the market watchers are reporting that the MB manufacturers will 'probably' under go some consolidation mid to late 2001, meaning that the large companies will be buying up the small companies.
Personally for me, I chose the Iwill KK266-R (the R is for the RAID version).
The reason for my choice was rave reviews, it has an ISA slot, the RAID controller is made by AMI, and this MB manufacturer has an OEM presence which means it will probably be able to stand on its own feet financially- unlike Abit! It has the 3 phase power configuration like Abit introduced last year, and the board layout (specifically the power connector placement) is very nicely done, along with 3 fan headers (connectors)on the MB!
The only neagtive item I could find about the board is the placement of the AGP slot... with a full length card in it, the DIMM slots are rather crowded and to remove a stick of RAM you will probly need to pull the AGP card.
Lastly the Iwill uses the A1 stepping of the KT133a chipset which is reported on these forums as well as other places to do the 266 FSB thing better than the A0 (initial/original) stepping of the chipset that Asus and Abit completely bought up upon introduction of the KT133A chipset.
I agree with MCS that first generation DDR/AMD760 is not yet ready for prime time. The boards along with their higher priced DDR memory are not worth the cost, bang for the buck wise to me or many other reviewers. I personally do not want to pay for bleeding edge technology that is essentially beta. I do believe that the DDR platform will have a place in our future, but not just now. I don't want to pay a premium price for the privledge to beta test the newest latest and greatest technology.
