On the CPU/Motherboard frontier, a top-end Intel bundle is
there for you to pick up if your wallet is big enough for it.

Intel 955 Extreme Edition Dual Core CPU and the Intel D975XBXLKR
Motherboard! The CPU goes for SGD$ 1716 alone while the motherboard
goes for SGD$ 432 alone at Cybermind #04-26 Sim Lim Square.
Bundled together, the two go for SGD$ 2135. Not cheap, but this
IS one of the most high-end setups around.
