Had the same thing before. Apparently it's grease from the thermal pads or so I read. 

 
Totally fine. It's some of the oil from the thermal pads. It's not electrically conductive, so there's no worry. At most, it will attract some dust. 
 
You can clean it off with some isopropyl alcohol and a lint-free cloth. 

It happens with some pads. Again, it's somewhat common, and won't hurt the card. 
 
Find alcohol with the highest percentage. It will have less water. Though you can use pretty much any percentage. You don't need to dump it on the card. Only moisten the cloth, clean off the oils, then let it dry before putting it back in the PC.

Why does it do that anyways? Is it normal? Does it need to be replaced? Are you sure I can use isopropyl alcohol with what percentage? I'll have to find a lint free cloth then. Thanks for your help tech support!

When the cards heat up, it heats up the thermal pads which causes the oil in the pads to heat up as well. This causes the oil to become less viscous and allows the oil to seep out of the pads and to be visually seen. This typically occurs when the cards are at high temperatures for extended periods of time. This oil is harmless and non conductive and can be easily cleaned using 91% Isopropyl Alcohol and a microfiber cloth.
 
Just wanted to give a little bit more of an explanation :)

Don't wipe

It is fine, I'd just plan a tear down in 3 years if I were you. Even if you don't do a full tear down to reapply TIMs it will still perform without problem, just slowly getting warmer operating temperatures, and throttling. I recommend using your hardware for as long as possible, these products have a real cost of resources and environmental impact. The best thing you can do is get the most out of them. Just my opinion though.

Since these are my specs. I need some honest answer here because I am tired of assuming I am ruining my components with too much power. I know I have been told from experience there is no big deal in using more greater power for your system but I was told differently the PSU is important since it regulates every component properly.
 
CPU: Intel Core i5-3570K overclocked to 4.4ghz (Auto volts only)
ASUS Sabertooth z77 motherboard
GPU: Nvidia GTX 1060-6GB SSC version from Best Buy.
SSD: Samsung 830 256GB (2012)
HDD: WD Black 1TB (2010)--bought from a local shop.  (I will pay attention to the dates and recent data such as write and reading stats) May consider a Seagate HD since they are better.
HDD: WD Blue 500GB (2010) bought from a local shop. (I will pay attention to the dates and recent data such as write and reading stats)
RAM: Corsair Vengeance DDR3 1600 C9 4x4GB (bought in 2013)
MBD: Asus SABERTOOTH Z77 Motherboard (2013) Been running SOLID very good for years! I do want a i7 3770k just to have hyperthreading but I doubt I should.
PSU: EVGA 850 BQ Power Supply
Monitor: BENQ 1920X1080p (5/18/2014) Yes I know it's old! LOL!
Operating System: Windows 10
 
Is my PSU too strong for my video card? What gives? I saw the specs say minmium of 400 watts? Did I overpower my PC too much?  I need some expert advice from EVGA tech support because I don't wanna kill my system. 
 
I do need a new SSD and Hard Drive anyways. I cannot upgrade to a 8th generation because it's expensive and I am behind on bills. My birthday is coming up and I am trying to figure a way to rescue my system so it can run much longer than before. I'd love to overclock my cpu more but I don't have any experience in using custom voltages but theya re on auto volts and it's stable. I never have problems. So I really don't know what to do. I honestly think my video card might be too strong for my Ivy Bridge and maybe my PSU is way too strong? I was told anything above 400 watts recommended specs are fine. I dunno if I am wrong. I am tired of misdiagnosing my pc so badly. cable plugged in my motherboard 3g slot instead of 6gb slot for Hard Drives.  I'll contact tech support I have to.

I think you have it all well handled. Personally, I'd plan to pay things down using Paypal's bill me later program. Not paying interest is so nice. Or save up. Having a need to fill like being in games with friends during the holidays is a very reasonable demand if you can meet the costs.

The usage of thermal pads has increased and possible pad material type has changed. There seems to be oil in the pad composition which probably helps with heat transfer. Oil can and will leach out over time
 
Just like an automobile engine with a few miles on it. There might me some oil staining here and there but no real oil leak
 
As to your power supply. You cannot kill your system with an higher rated power supply, just your power bill
 
In reality you want a power supply that will be 40-50% higher then what your expected max wattage would be. Power supplies actually work at their best efficiency at about 50% load. What that means is at say 10-20% they are pulling more wattage from the wall then what they are outputting, where at 50% load they are pull almost equal to what they are outputting

Okay thanks guys I appreciate it. Wish EVGA would sell thermal pad kits and information how to do this. I would love to re-apply thermal on this video card. Is there any danger on my card if I do NOT clean the oil on the card? I haven't bothered to find 99% rubbing alcohol in my local shop it gets frustrating I cannot find one. I may need to visit one last place and that's Target. Hopefully they have it lol.

Does anyone know if I have to order thermal pads to replace on my video card? Plus is it bad to use the original thermal pads? I plan to take it apart and re-apply thermal. I would love to order a backplate but probably down the road. For now I just wanna re-apply thermal. I wonder if there is a backplate that fits EVGA 1060 SSC 6gb
