Do CPUs actually make noise?
-Deozaan
If you put them in a microwave...
The CPU fans of your Intel processors were crap. An after market CPU fan would have made a lot of difference. Never had noisy stock CPU fans...then again every 6 months or so I thoroughly clean out the accumulated dust in each PC. Graphite or other forms of lubricant I apply as well (when necessary).
Back to the topic: Depends on the main task of the PC, to be honest. I have had good experiences with multi-cores from both AMD and Intel. In the days of the single-core CPU's I rather used AMD. Most of my servers still use those CPU's as they are still going strong after 10 years.
However, I do work with a lot of i5 (2nd gen) and i7 CPU's (1st gen) in workstations & servers as well. To my knowledge, AMD is better when you work with multi-threading software. Price wise there isn't much difference between AMD or Intel here in Paraguay. Whatever money you save with the AMD CPU, you have to spend on more expensive motherboards.
As there isn't that much software out (for consumers) that actively/efficiently uses multi-threading, my choice today would be to buy Intel for raw calculation performance.
Don't have experience with the AMD APU's, but I do find these interesting. But these are not available through the regular retail channels over here.
