I am Extremely happy with my ecs k7s5a..
Do a search for ECS K7S5A in the forum and you'll find a few threads with more details.
so much infact I bought 2 more just the other day...one to upgrade my secondary system and the other may be the basis of the system I build for my church's projector PC. I still haven't heard what my budget is nor whether they prefer an AMD or Intel system. If they go intel i'll use the extra board to either build my sister a christmas PC or build myself a 3rd F@H system to attach to my LAN...
If your looking to overclock it though you'll most likely be disappointed as it doesn't support squat(officially that is)
Have to get the hacked BIOS from ocworkbench's ECS forum to get additional FSB options and in order to get vcore and multiplier options you have to do a rather difficult solder/dipswitch MOD.
THE BEST VALUE/PERFORMANCE BOARD OUT THERE!!!
best overclockable/value is the epox 8kha
There will eventually be better O/Cable SIS735 due for release, but I think they are going to get to market to late to make much of an impact since the KT266A is out and already has a couple OUTSTANDING boards released to market(epox 8kha+ ,shuttle ak31a, msi something PRO,and some gigabyte board.
