Not really.
The M810LR uses the SiS chipset's internal LAN engine - you get lower ping and zero PCI bus load, as opposed to the PCI Realtek chip on the K7SEM.
Both boards do use the chipset integrated sound engine, however the M810LR has a 4-channel codec.
Finally, you get an AMR modem card for free with the M810LMR, and this board has been on the market for the longest time.
As for quality, ECS and PC-Chips are two different outlets of the same company.
But, MCS, why on earth would you want to buy a mainboard with integrated VGA, only to stuff a graphics card right away? Think again! You'd rather want to use something like PC-Chips M831LR.
