Dual-core dual-opteron system pricing

I've been using a dual-Opteron (twin 246s) system as my main workhorse machine for a while now. It still works well, but the Tyan Tiger K8W pipes all memory accesses from the one CPU through the other CPU, which makes it slower then it could be. Plus the K8W doesn't support the newer dual-core Opterons (at least not according to Tyan's CPU chart).

The newer Tiger K8WE (S2877ANRF) has a different memory configuration along with an NVIDIA chipset (instead of the AMD chipset). It's also a PCIe motherboard, so there would be some upgrade potential. Looks like it's available for around $275 to $375.

However, the Opteron 265 (dual-core, 1.8Ghz, 2x1MB L2 cache) is around $720 each. The Opteron 270 (2.0Ghz) is $900-$1000. The Opteron 275 (2.2Ghz) is $1100 and the Opteron 280 (2.4Ghz) is $1350. Just a *little* pricey. In comparison, the Opteron 246 chips (2.0Ghz, single-core) are only $225.

Memory chips are $120 each (Corsair CM72SD1024RLP, PC3200).

Eh, I think I'll wait until the Opteron 270s drop below $500 each. The chips are still too far up the price curve for my tastes.
