Solve : Intel i5 vs i7?

1.	Solve : Intel i5 vs i7?
Answer» Looking at Intel's i5 2500 (sandy bridge) and i7 2600 (sandy bridge) I notice three main differences: 1. The i7 has twice the threads 2. The i7 has better intergrated graphics (if that works how I think it does then it's something not that useful) 3. £80 more for the i7 [hardly worth mentioning the 100MHz clock speed difference] When CONSIDERING this processor for a machine with it's own dedicated graphics card, that takes the intergrated graphics out of the EQUATION. So are the 4 extra threads worth it? What performance difference would one expect to see? With Intel's i7 970 & 990X I can't begin to justify the money for these, they look awesome but not £800 awesome.Processors Have neither threads or integrated graphics.By threads, you mean hyper-threading, right? According to the article I've linked to here, Hyper-threading is disabled on the i5 processors but is enabled on i7's. The article refers to Intel's "Sandy Bridge" processors. I don't know whether the i5 and i7 processors come in other flavors.

Looking at Intel's i5 2500 (sandy bridge) and i7 2600 (sandy bridge) I notice three main differences:

1. The i7 has twice the threads
2. The i7 has better intergrated graphics (if that works how I think it does then it's something not that useful)
3. £80 more for the i7
[hardly worth mentioning the 100MHz clock speed difference]

When CONSIDERING this processor for a machine with it's own dedicated graphics card, that takes the intergrated graphics out of the EQUATION. So are the 4 extra threads worth it? What performance difference would one expect to see?
