Things have stirred lately with Chinas ban on crypto mining and many used GPUs will flow the market probably. But should you buy a used GPU?
Short answer: NO, long answer: keep on reading to find out why.
GPU shortage and its cause
As you all know by now, we live sadly in a world struck by a global Pandemic. Due to this awful disease and measures taken against it, many people are either working from home or are at home making the manufacturing of new chips problematic while demand on the market has raised.
Throw into that mix crypto mining which has raised in popularity and you have, well today's market where we have GPU shortage.
Now with the latest news that China has banned the mining of cryptocurrency, there is to be expected that at some point in time mining cards used there will fit the market in the whole world.
Sadly even with a large quantity of GPUs that will become available, the overall price of cards will not be much lowered I am afraid since demand is still very high and many people would not want to purchase used mining cards and neither should you.
Be prepared for the worst scenario
Although this sounds very pessimistic and in most cases, it will not turn out to be true, you should always prepare yourself mentally that you might be in that lower percentage that will end up with a really bad GPU.
What has come up to be absolutely true when considering GPU that were mining is that if anything at all can be done to GPU in order to increase performance, it has been done. Miners want to optimize and almost every GPU if could be overclocked, it was overclocked.
Extensive mining also means that thermal paste has been dried and it is pretty useless at this point and there is a very high chance that fans and heat sinks will need much cleaning or even replacement raising the price of the card itself for mentioned paste, fans, and heat sinks.
There's no way to tell what the previous owner might have done with a graphics card when you're shopping online, so our advice is to assume the worst. Don't trust the seller to give truthful information. Any listing that says it was "never used for mining" at this point is probably a lie.
Age of the GPU matters
Date when GPU itself has manufactured really matters. Newer cards even if used extensively have been used for a much shorter period of time and are not so damaged were ones produced a few years ago have seen a lot of action.
Let’s say that you get RTX 3060, In the worst-case scenario it has been mining since late February of 2021 and basically, it is still under warranty so it should behave OK and put some good work in gaming even in that state.
On another hand, if we take for example GTX 1080Ti which is 4 years old GPU things start to change drastically. 4 years GPU could be worn out even if it was used just for extensive gaming sessions let alone for mining.
No return policy and seller rating
Most of the time you will run into a product that cannot be returned or no refunds policy. This should bring a red flag right away and deter you from purchase.
Sellers with the highest ratings are more trustworthy since many of them will not want to destroy their reputation but these will probably not even have these kinds of merchandise in their store.
Buying with a poor rating seller and no return policy on a product is just asking for trouble. And although some stores do have arbitration and will stand on the customer side there is no guarantee for that and it will take too much time to process.
If you really must buy a second-hand GPU
Of course in these troubled times sometimes due to malfunction or any other reason, there would not be another choice than to buy a second-hand GPU.
In this case, if there is no other option consider sellers with many positive ratings. If you can buy locally that would even be better or the best-case scenario would be if you could visually see and inspect GPU itself in order to see in what state it is.
Look for warranty stickers to see if they are thorn and the card has been tampered with. Also take a good look at screws, if they have scratches card has been opened, probably to replace fan or heating sinks which means that it has worked a lot.
Conclusion
It is very difficult to give the best possible advice on this situation since of GPU shortage, but I would much prefer a new GPU with lower performance than a hi-performance one which was mining.
Razer is a well-known brand among PC gamers and users, it started as a peripheral manufacturer focused on keyboards and mouse but after years passed Razer expanded its inventory offerings. It soon started offering headphones and lately has branched into wider product lines like gaming chairs and protection masks.
It is not a big surprise that Razer is expanding into other branches of the PC industry. This time, however, it has revealed not one but three new hardware for your PC. Case fans, all in one liquid cooler and power supply.
There are not many details about the products themselves but one thing is one hundred percent confirmed, they come with Razer Chroma, all of them, even the fans.
Most interesting for me personally is Razers Katana, the power supply unit. It is a modular power supply ranging from 750W to 1200W with the additional option of Titanium rated one with an impressive 1600W of power. Power supply will start shipping in early 2022 and at the time of writing this article no price range has been released.
Hanbo liquid cooler will feature an optimized intake design so it can ensure greater heat transfer and fluid dynamic for improved reliability and silent operation. Radiator comes in 240mm size with two fans and a larger one of 360mm with three fans. The pump will be able to rotate in any direction of full 360 degrees so it can fit in any case. Hanbo will be released in November this year but no pricing has been released so far.
Kunai fans will boast high static pressure performance with lowered noise. They will go as far as 2200rpm for the 120mm version where the 140mm version will go up to 1600rpm. They will come with addressable LEDs and up to eight fans will be able to be connected to Razer’s PWM fan controller that will come with a magnet at the back for easy attachment to any steel part of PC casing.
PWM will use Razer’s Synapse software to customize pulse width modulation in order to improve airflow and noise. PWM will be priced at $49.99 in the Razer Store and it is available for preorder. Fans are priced at $44.99 for one 120mm or $129.99 for a three-pack of 120mm. One 140mm will go for $49.99 and a three-pack will be $129.99. 
When Task Manager opens, click on the startup tab on top.
Once you click on startup you will get a list of applications that are set to be started when Windows is booted.
You can now click on the application and then click on disable on the bottom button, the application status will update in task manager to disabled and it will not be booted anymore when Windows starts. In this same manner, you can enable back some applications if you changed your mind about them.
Please note that some applications are using some services and must have them running or they will not work properly. The best practice is to disable applications you are positive you will not use or use rarely so you do not want them to slow down Windows.

Interesting information has come out from Microsoft, Windows 11 dark theme will include a different sound theme from its standard light one.
When in dark mode on Windows 11, the system sounds generally become softer, and they echo a bit, creating a more soothing experience that matches the overall look and feel of the dark mode. Flipping back to light mode brings the system sounds back to their normal level.
However, even though the light model has slightly louder sounds than the dark mode, Microsoft has taken great care to make sure the audio is more soothing, according to a report from CNBC.
The designers of Windows 11 took inspiration from an approach called calm technology. Microsoft’s Christian Koehn and Diego Baca wrote about calm technology in a post on Medium. In it, they said, “Windows 11 facilitates this through foundational experiences that feel familiar, soften formerly intimidating UI, and increase emotional connection.”
According to a Microsoft spokesperson in a statement to CNBC, “The new sounds have a much rounder wavelength, making them softer so that they can still alert/notify you, but without being overwhelming.”
