Thank you for all of the replies, guys! But I think you misunderstood me. I've said "the GPU is a Chinese replica" earlier. I don't doubt if it's a legit one, I'm sure that it's fake.

My question is more like - is there any way I can run some miner (old version, etc), so I can see the hash-rate?

This is the GPU-Z screenshot:

What I've tried so far:
1. Installed the driver 390.77 from the Chinese CD - Windows DOES recognise the card
2. Installed the driver 390.77 from the NVidia website - Windows DOES recognise the card
3. Installed the driver 465.89 from the NVidia website - Windows DOES NOT recognise the card

Errors so far:
ETHMiner: Out of memory
LoLMiner: Problem in loading kernel
PhoenixMiner: Compute 2.1 (minimum 3.0 required)

I'm guessing that if the GPU's chipset is an old one, I can use some old miner version to mine? Or I'm mistaken?

It's a Fermi 2.0 Card, a GeForce GTX 560M, a GTS 450 or GTX 550ti.

I don't belive you can mine anything profitable with those nowdays.

They current models they are selling usualy looks like that (with green stripes too):
