As the description says my windows 7 says that my CPU is only at 4.0GHz and not at the 4.7GHz it should be. If anyone can help with this problem it would be greatly appreciated.

Specs:

CPU: AMD 9590 Black Edition w/liquid cooling

MOBO: GIGABYTE GA-970A-D3P

OS: Windows 7 64 bit

RAM: 16 GB

Graphics card: 7970

drivers up to date

The newer CPUs have dynamic frequency changes based on load and temp. Try CPU-Z and see what it shows. You can also manually set the frequency if need be.

Also be advised that there are only a handful of AM3+ mobos that have a sufficient VRM design to handle the FX-9000 series CPUs which have a 220w TDP. I do not believe the GA-970A-D3P officially supports the FX-9000 series and thus it may very well limit the frequency under heavy load as the VRM overheats and cycles down to keep from burning up.

Gigabyte has had VRM issues with all 8-core AMD FX processors and finally redesigned the VRM circuits on the "FXA UD" series mobos. These are the only models that can properly support the 8-core FX processors under heavy load IME. Within the XFA group there is only a couple mobos I believe that support the FX-9000 series.

Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.

The FX-9590 is not a supported processor for that motherboard.

The ASUS Sabertooth 990FX R2 is what I would recommend.

I recommend either the Asrock 990FX Fatality Pro if you can still find one or the Asrock Extreme9. Both of these Asrock mobos have a proper 12+2 phase VRM circuit to deliver sufficient power for 8-core FX CPUs and both are approved for the FX-9000 series models. IME both are better quality mobos than Asus or Gigabyte mobos and the Asrock usually cost less. IME, Asrock customer support is lightyears ahead of Asus and Gigabyte in my 20 years experience building many highend PCs.

Asus mobos are pretty over hyped IME. Independent testing shows that the Asrock mobos OC as well or better than the Asus and Gigabyte mobos. The only two mobos that I have had fail in 20 years of building highend PCs were both Asus. Asus tried to replace a 2 month old mobo with a POS refurbished mobo that someone had hand solder repaired. It was covered with dirt and looked like they found it on the side of the road. Asus also uses multiple companies to produce their mobos so you never really know what you'll end up with. You can read about customer support for the various mobo companies and it ain't pretty.

Even though I like the Gigabyte Ultra Durable series mobos, Gigabyte denied for two years that their AM3+ mobos had any issues with the VRM circuits and 8-core CPUs despite me proving to Gigabyte in their own mobo testing, the VRM issue. Now two years later they come out with a new Rev. (FXA) and a redesigned VRM circuit that can properly handle the 125w, 8-core FX CPUs. I'm not sure I'd trust Gigabyte again, especially with a FX-9000 series CPU that has a 220w TDP.

Make sure that whatever mobo you buy fully supports your FX-9590 and that it has whatever features you may need.

Asus Sabertooth 990X R2.0 is what I would get. Personally. 

Quick Review of product here

http://www.overclockersclub.com/reviews/asus_sabertooth990fx_r2_review/

It also beats the competition in maxium stable overclock as to be expected of an asus board in this price range. 

No need to worry about quality either independent 3rd party sources have them listed as the lowest return rate in the industry just a year or two ago.
