Pros: I would like to say something good about this 9590 CPU, I know I should but it is very hard with its out of box default turbo speed instability. I will say the previous generation top of the line AMD desktop chip 8350 was very reliable both in turbo and normal modes.

Cons: Will not run stable a 100% usage at default out of the box turbo setting. To get this CPU stable I had to turn off turbo making it not exceed 4.7Ghz . I use a fairly high end custom water-cooling system that is valued at more than three times the current price of the CPU. In my opinion this is simple not acceptable and is false advertisement as far as I can determine. If you are only a gamer or just a causal user / tester this might be a great CPU. It will boot up show you 5Ghz make you feel good about yourself however it is really a “placebo extra strength.” This chip will work most of the time just don’t put it under sustain 100% load.

I use three main computers in my home office extreme hobby / recreation. The three computers currently have the following three CPUs i7-990x, AMD 9590, and lastly a i7-4960x. I not an over-clocker anymore, I find as I get older both reliability and stability are more important to me than squeezing that extra 5 to 10% . This is why I buy the highest end manufacture certified clocked CPU at the time and live with it until I need to upgrade. Until recently in my AMD rig I used to have a 8350 CPU in a Asus Sabetooth 990FX GEN3 R2 and was very happy with the results of that CPU, it worked exactly as advertised. Other than enabling memory profile timings no other setting was required on the motherboard. When I got the 9590 back in March of 2014 I just turned it on ran very few tests and turned it off. Everything seemed to work great and I assumed this is the same modern quality from AMD that I have grown to respect. So no need to run a full battery of tests. One week ago I ran some compilation batch jobs for this first time on this 9590 and as a result I got to see some of the new blue screens of death in windows 8.1. The problem is when the CPU goes to 100% for any sustained length of time and my custom batch jobs will usually last for last 4 to 6 hours on the previous 8350 CPU. On the previous generation 8350 CPU after 6 hours the CPU would never get above 42C with my current CPU liquid cooling loop for this AMD system. The new 9590 idles at 40C and after 5 minutes of 100% use it then goes to 49C and after 7 minutes of use climbs to around 55C and about the 12 minute mark it starts to fail at 59C to 60C. I switched out three different water blocks in an attempt to reduce the temp but all three types seem to preform almost the same. I used 4 different types of TIM but settled back on Arctic Silver 5. I did a lot of research on this stability issue and many people report having temperatures much high than mine so then I thought it might be a power supply issue. However I have 2 higher end 1200 watt PSU used in parallel in this system and I hooked a multi-meter and oscilloscope to the power supply providing motherboard 12v just to see confirm that it was not a voltage, or ripple issue.

Other Thoughts: Then I thought I might have a bad motherboard, RAM, and or CPU issue. So I swapped components out with my buddy who has the same AMD 9590 purchased 3 months before mine. He uses it as his primary machine so I could not test with his computer for long. He uses a Gigabyte 990fx-ud7 motherboard and has a different brand of RAM as well. First before changing anything out I ran my batch job on his computer. Not a big surprise it too also failed but his went to 60C then blue screen and rebooted almost simultaneously to not build a crash file. Then for other test I moved my custom liquid cooling solution to his computer. I removed his all-in-one AMD OEM water cooler I think it is a Corsair rebranded, after moving my cooling system to his computer we got the same results. Lastly I turned off the ability for my computer to go into “turbo” mode making the CPU not exceed 4.7Ghz, success it works perfectly 100% reliable batch jobs run 6hours and the CPU never exceed 51C. This is great except I did not buy a 4.7Ghz CPU I bought a 5Ghz CPU under turbo core mod.

The water cooling system for this AMD 9590 CPU has these components:
HX-CU1320V radiator with 8x delta 192CFM fans in push and pull configuration
1 liter Danger Den reservoir
Fluid = 80% distilled water, 18% propylene glycol, 1% Iodine, and 1% benzalkonium chloride
Tygon R-3400 ½”ID ¾ OD
Two pumps in push and pull configuration Swiftech MCP655-B
CPU block XSPC RayStrom Copper Edition

I believe my testing methods to be valid and this CPU cannot sustain 5Ghz for prolong lengths of time.

Pros: The software is very complete and well done. The looks of the mouse make it one of the most aesthetically pleasing ever. The lighting is very adjustable making it easily adaptable into anyone’s existing motif of color in their current gaming IO devices.

Cons: When I got my mouse box it was pre-opened (seal broken) inside the sealed Newegg package. I don’t believe this is Newegg’s fault as I have purchased EVGA products in the past as an earlier adopter from Newegg and they were pre-opened from EVGA’s distributors. (example: EVGA e762 4-way SLI) The instructions from EVGA are wrong on how to remove the top cover of this mouse to add weight. If you follow the instructions you could damage your mouse. Contrary to the instructions in the manual you will need to apply pressure first to the forward part of the mouse (the area closest to the cord) pushing back. This will release the catch and the top will pop right off. Replace or add the weights with whatever you like. How this got by QA is a mystery to me, I have to take off two stars for pre-opened package and documentation that could lead to damage.

Other Thoughts: I had high hopes for this mouse as a replacement for my current well used G9x. Unfortunately this mouse is too small for my large hands regardless of adjustments. I have used it for five days now and I am going to put it on the shelf with my RAT 7, Mamba, and G502. This is just a personal preference this is not the right mouse for me, however it may be perfect for others. So I went looking for another G9x today, and there seems to be many people in the exact same predicament as myself. Used G9x on a popular reseller site are going for two and half bills now. That is almost four times what they sold for new. This is not a review about the G9x I just wish somebody would build some replacement for this old out-of-production super gaming mouse.
