Well somewhat but I think the release of the i5 750 really did damage to AMD's image as bang for your buck.
Not really. IMO Intel has some great deals on great processors but I consistently see AMD come out with cpus that are less money than Intel's and yet are great performers.
To the OP:
If you are just looking for a computer to run Windows 7 (nothing special needed) then I would recommend any dual core Intel or AMD. Since you posted that you wanted a clock speed around 3.2 check out
Athalon ll Regor: $75

If you want Intel,
i3- 550: $150

The i3 has hyperthreading so it will show up with 4 cores in task manager but it is not a true quad core. For $150 you could just get a quad core from AMD.
In my opinion, Intel has a better architecture and is a bit faster (not in Mhz, the way it handles information) but AMD will still give a great amount of performance.
Just for an example I built my system in my sig and helped a friend build a rig with a i7-930. Both systems are very quick neither him or I can tell the difference when running regular applications ie: excel, winrar, virus scans, etc... The only time that I can tell that his cpu is better than mine is in benchmarks.
For a regular home office computer I would recommend AMD. Mainly because they are cheaper and the performance difference will not be noticeable in a lot of situations.
I guess I want to know, apart from running Windows 7 what else do you want to do with this pc? How many cores do you want? What are you looking to spend on a cpu?
