Is my PC fast enough?

My old PC is broken and I want to buy a new one. But I’m not sure, if the recommended hardware is good enough for real developing. I want to make a bigger indie game with less detailed graphics, because I’m alone. I don’t know, if this will be fast enough, especially, when I’m using Visual Studio for C++
Processor: round about 4x3GHz
Graphic Card: 4GB VRAM
SSD: 128GB
HDD: 500GB

The owner of my computer shop thinks, that this is not enough.

Well, here’s the recommended specs from the UE4 wiki.

  • Desktop PC or Mac
  • Windows 7 64-bit or Mac OS X 10.9.2 or later
  • Quad-core Intel or AMD processor, 2.5 GHz or faster
  • NVIDIA GeForce 470 GTX or AMD Radeon 6870 HD series card or better
  • 8 GB RAM

This has not been updated for years, for a new desktop computer I’d adjust it to:

  • Recent Intel i5/i7 or AMD Ryzen/Threadripper processor
  • NVIDIA GeForce 1050ti GTX or Radeon RX 460 or better
  • 16 GB RAM
  • And a 256GB+ SSD with extra HDD space

Buying previous generation GPU and CPUs don’t often save much money per performance, unless a new product just came out and they are trying to get rid of stock. The amount of vram a GPU has doesn’t tell you much about how it will perform.

Good advice from Zak. In game dev you always need more than you think.
I agree with the shop owner too, you didn’t even specify a Graphics card?

The memory looks sufficient or ok for now, but all the rest I’d worry about…
500GB isn’t enough for digital content, its general home use PC territory.
Buy an external hard drive too, even if you opt for Cloud Source Control…

GPU rating sites help with selecting the right GPU / information overload.
My rig is on the left… On the right is just one possible desirable option etc.
Don’t go any less than mine, unless its a cheap second-hand throwaway!

UE4 Goal:…Force-GTX-1080

UE4 absolute bare minimum:…eForce-GTX-470

But for which things should I need this? It ran a bit slow on my old computer with 4gb ram and 2x3ghz

Dual core CPUs will be slow for UE4, and I’d guess your GPU was lacking as well.

It was slow at compiling C++ Code, but it worked well for all other things. And the graphics lagged only with high settings. Low and mid grapics had 30fps, higer settigs hat round about 5 fps.
