menetlaus - thank you, I have a hard time wading through the sea of parts and specs. I only know to look at the main numbers (ghz and cores for cpu for example.) So that is helpful, is the ipc (instructions per clock) a readily available spec for cpu's online? And are there other factors to help me wade through the information on cpu as well as other parts? (ram, gpu, MoBo...)
You can always look here to see which CPU's are best for the money. http://www.tomshardware.com/reviews/gaming-cpu-review-overclock,3106-2.html
I prefer the second last page of that article, doesn't just show currently available parts but includes where older hardware stacks up. There is a similar article for GPU's if you want to read it over too.
One word of caution, the rankings/advice in the articles is based on a gaming system, if looking for something equally good for photoshop/rendering/other heavy CPU usage it may not give the best advice.
To answer your question, it is not so easy to find good literature on IPC. I think it is mostly because it gets very technical and complex very fast so it doesn't lend itself to be easily reportable. Most of what I have read on it comes from the broader articles written for new CPU architectures, and is from summary statements that say something like "new should be about 10-15% faster at same clock rate compared to the previous generation".
