AMD vs NVIDIA?

I think NVIDIA have more superior performance than AMD.and Cost is also reasonable as compare to AMD. 

user friendly also.

I Bought NVIDIA Quardro at  ₹13,770

Its Bindless textures Shows high performance .

NVIDIA is Best.

For about the same price, Nvidia is a little faster and uses a little less fuel. Nvidia is the winner. Nvidia wins in the majority of categories across a wide variety of titles. AMD can compete with the RX 5700 and RX 5700 XT, but it can't compete with the 2070 Super or higher, and it's essentially equal to the old GTX 1080 Tic.

No real crashing issues with either driver set that I have ever found. I'm currently using AMD, previously had Nvidia. Right now, there is a lot of talk that the AMD drivers put 20-30% less load on the CPU. Hardly makes a difference if you have a relatively high-end CPU with 8 or more cores, but anything less than that seems to suffer worse when paired with an Nvidia GPU. Apparently it's due to the fact that AMD are now using hardware scheduling on their GPU's, while Nvidia is still using just software scheduling. For those reasons, you might want to go with AMD right now.

But in the greater scheme of things, you can't buy anybody's GPU's right now anyways, as they are all sold out. So unless you have an existing GPU, you really have no choice what you can run right now.

AMD RX 5000 series cards had a lot of problems until driver version 20.4.2 which came out April of last year. After that, there really haven't been any problems. There are a lot of people who make comments about computer tech but they're not up to date with what's going on in the tech industry. 

The Radeon RX 5000 series is based on a brand new architecture, which took AMD several months to work out all of the bugs on the Driver level. The RX 6000 is a refresh of the RX 5000 series. I haven't heard of any Driver level problems with the 6000 series as of yet.

Both brands have a good and a bad side. As far as Nvidia goes, The talking heads on Youtube will tell you that 8gb or 10gb of VRAM is enough but it won't be here in a couple years. AMD's RX 6000 series cards might come with a decent amount of VRAM but the Nvidia RTX 3000 series cards are better with Ray Tracing. In 2-3 years you will probably see more games that gobble up VRAM and these games will be able to make good use of Ray Tracing. Power efficiency between the RTX 3000 and RX 6000 series is about the same.

AMD gained a bad rap with messed up drivers for the RX 5000 series cards and the power efficiency of some of their past GCN cards like the Vega 64 and R9 390x was pretty bad. AMD has done a lot to shore up the gap with the RX 6000 series cards. If you can somehow manage to get an RX 6800 for around $600 then that would be a good buy.

AMD CPU plus nvidia GPU; that's the best combination, at least from my experience.

Don't believe what other people say. If you want to be happy, do you own research and then make your own decision Do what you want to, not what other people tell you to;

maybe you want to review the 'best buy' products as selected by the editors of gaming oriented websites ... internet search for them

You left out the BEST One.   Intel i9 CPU.
