I'm not sure why you're excluding Opteron/Phenom a priori.
I would at the very least benchmark the (QM?) applications on each
architecture, using proper optimization. Also, price/performance
ratio instead of absolute performance might be relevant.

SunFire X2100 M2 are not bare motherboards, but IIRC a complete
barebone sells for about 470 EUR sans VAT. IPMI, 8 GByte ECC, 4 GBit NICs
(unfortunately, 2x nForce and 2x Broadcom). Only dual-core at the 
moment, but that's bound to change in a month or two. Optional
riser board can take x16 PCIe if you're considering CUDA & Co
a later option.

(Disclaimer: I don't sell them, but I use them).
