Would like to buy a laptop (please see link below). I think it's good for the price. You are welcome to share your opinion on the laptop or recommend a better one.
Unfortunately, the laptop in question has no operating system.
My question: I can buy and install an activation key (Product Key) Windows 10 for about 15-20 euro online, e.g. At Softwarebilliger.de? Or is there a catch?
In theory, this is possible, you just have to load Windows onto a USB stick and then start the laptop using the stick
You can certainly do it as a layman, right?
Can you also say something about the laptop?
Price-performance good? Is intended as an all-rounder.
The fact that there's no operating system is not a problem. As you said, you can buy a product key for little money. There's usually no catch if you choose a reputable dealer. I can also tell you where the price differences are coming from, in case you have concerns.
As a rule, a distinction is made between retail licenses and OEM licenses. You pay significantly more for a retail license than for an OEM license. The retail license includes packaging, a Windows DVD and Microsoft support. With the OEM license (formerly system builder license) there's usually only one product key. But that's not a problem because you can easily create the installation disk yourself for free.
If you don't intend to gamble, the hardware of the laptop is fine. The processor has a lot of power, 16 GB of RAM are completely sufficient and a 1 TB SSD usually also offers enough storage. However, if you want to play games with high demands, then you should get a device with a dedicated graphics card. It is also questionable whether you need 16 GB of RAM at all. Personally, I would get by with less memory. There you could possibly still save.
I'm an occasional gamer. For FIFA and GTA in FullHD medium settings it will fit, according to Youtube Videos… RAM should have 2666 MHz, doesn't that slow down the CPU?
Should actually be doable.
I can hardly tell whether the price-performance ratio is good because I would then have to compare more. But it's solid as an all-rounder. You won't be able to play the big games on Max Ultra with it now, but that's never particularly good with a laptop anyway, so I would always recommend the PC. But things like FIFA shouldn't be a problem. The RAM is perfectly fine with me 3200mhz and DDR4.
RAM should have 2666 MHz, doesn't that slow down the CPU?
In my opinion, that's clear.
Strange is Otto and Media Markt says "16GB, Dual channel, 2xDDR4-SO DIMM 3200MHz" and the official Captiva website says "2666 MHz"
Let me summarize briefly: As an office internet chess card PC, it is completely sufficient, if not oversized, but the friendship certainly doesn't go any further, because a Vega 6 is no good. You'd have to turn your attitudes down enough to get eye cancer. But your decision
About the laptop, that depends on what you want to do with it. Office, games, videos - everything has different requirements.
About Windows: Yes, you can buy a key from such shops. The catch is that the whole thing is partly a gray area. First of all, the question is always whether the keys are really legal or not. If the keys are legal (e.g. OEM bought up, volume licenses), that still doesn't mean that Microsoft sees it that way - there have often been lawsuits against sellers and possible problems in the past. If MS decides that the key is not legal and blocks it, then all you can do is try to take action against the dealer.
Another problem is that volume keys can often be used multiple times and are issued multiple times. But if one or two of the buyers activate the on several computers, then suddenly more licenses are used up and it no longer works. The dealer should also correct it and hand over a new key, but that's never quite safe.
In the end, there's always a question: If I want the all-without-problems solution, then I have to buy a "normal" license. If I can live with minor setbacks, then a key reseller.
Are you sure they are the same models?
I would make Win10 on it professionally.
