My computer is running ubuntu 12.04 (64bit), and I have a AMD Athlon(tm) X4 760K Quad Core Processor which is about 3.8ghz (and an Radeon HD 7770 GPU). Yet, when I type in cat /proc/cpuinfo - I get:

The important part of all this being, cpu MHz : 1800.000 which indicates that I have only 1.8ghz of processing power, which is totally wrong. Is it something with drivers or Ubuntu?? Also, will windows recognize all of my processing power? Thanks!

(NOTE: My cpu doesn't have intigrated graphics

What's being reported is the dynamic clock speed. Due to dynamic frequency scaling, your clock speed should only be at 3.8GHz under heavy load. Both Ubuntu and Windows will handle this similarly.

Note that you should be able to set your idle clock speed in the BIOS, but 1800 MHz is a perfectly reasonable setting.

so when i play games, it goes up? –  Nightshaxx Oct 31 '13 at 16:15
    
Yes, gaming should tax a CPU core enough to scale it to a higher frequency. If you're interested in seeing up-to-date system stats (mem usage, clock freq, temps, disk I/O, etc.), you may be interested in setting up conky –  konapun Oct 31 '13 at 16:24
