About me

Hello, my name is Kostiantyn and I am a computer hardware enthusiast. A few years ago I have started my YouTube channel, even though the channel is still very small with only ~28k subscribers, it was more successful than I thought. With the channel growth, I have got multiple requests for my services and to be able to fulfill the demand, I have established my company - One Gigahertz AB.

Right now I can offer:

Computer assembly for gaming and streaming.
Workstation assembly for video, audio, and photo production.
3D printing of different models and objects.
Upgrade of an existing computer.
Computer assembly education session for children and adults.
Computer hardware review and diagnostic.

Frequently asked questions

Question:
How much a gaming computer costs?
Answer:
5 000 SEK (€500) is the very minimum I would recommend. For 10 000 SEK (€1000) you can get a very decent gaming computer. 15 000 SEK (€1500) would give you a high-end gaming PC.

Question:
How much memory (RAM) do I need for gaming?
Answer:
For lag-free gaming, you would need 16 GB of RAM. It is recommended to step up to 32 GB of RAM if you plan to do some video editing or live streaming.

Question:
Intel Xeon is a server CPU, why do you use it for gaming computers?
Answer:
Intel Xeon processors are designed for expensive data centers. Many Xeon processors have identical specifications when compared to Core i7 and Core i9 variants, but available for less money.

Question:
Do you think I can upgrade my computer?
Answer:
Yes, most of the computers can be upgraded, which is cheaper than building a completely new one.

Question:
Can you help me overclock my computer?
Answer:
No. Overclocking is not a free performance. By forcing your PC out of specs you may lose the official warranty and permanently damage your computer.
