Premature optimization is the root of all evil (Knuth). Write everything in C#, profile, find the hotspot and optimize _that_. Additionally, writing all algorithmic code in C isn’t normally worth it.

It's the hell wrong about one important detail. There is no such thing as a "HT" or "Quad" instruction set, there are instead MMX/SSE instruction sets. So code for HT wouldn't be different from non-HT code. Core 2 Quad wouldn't be different from Core 2 Solo - the only difference is about whether you require and your CPU supports MMX/3DNow/SSE/SSE2/SSE3...<br/><br/>To support HT/Dual/Quad core, you have to write parallel code, by using multithreading or more recent techniques for parallelization.

That would be nice and support the message. Can you post the profiling data for comparison. That would be nice and support the message.
