It seems your platform is more suitable for a cluster. Great, and when are the products available? And is there any software support from you?

Is it too expensive for the platform?
The easy solution is:
And X48 level motherboard with CF support, about $150
Q6600 Processor, about $170
Two 4870X2 $1,100
Two Seagate SATA Harddisk 500G for Raid1, about $140
4*2G DDR2 RAM, about $150
PSU 1000W, about $200
A big box, about $100
That's all, in total, $2,010.
True, to a point.
Most people will not use a desktop board for a cluster.
Too I/O bound.
Finally the memory capacity of these desktop boards is pretty limiting. Typically 8GB maximum.
Generally a XEON or Opteron chipset and CPUs will be the choice.
Also, for most GPU/FPU performance work, the memory bandwidth bottleneck on the Intel product is too much of a negative factor.
Lastly, for clusters, most want a rackmount chassis.
We developed a 2U designed for a server board and 2 GPU boards.
The big challenge there is power.
We use dual 600W PSUs. One for motherboard, and one for dual GPU boards.
