ask your cousin Niko to test csgo
I don't understand why you are asking HLTV. Ask your cousin and he'll give you a better answer BECAUSE HE HAS THE ACTUAL FUCKING COMPUTER YOU WANT TO BUY.
get 300€ more and buy a better second hand pc
For the price, that's not a bad deal as along as the hardware isn't going bad. That GPU alone is about double that price brand new. The CPU is right about that price as well. Don't expect it to run newer AAA titles or anything, but it will play CSGO just fine. I have no experience with that CPU, but you should get well over 100fps. I'd guess you'd be mostly in the 120-180 fps range with low resolution and low settings, but that's just going by my experience with other hardware. Keep in mind RAM and motherboard make a difference in performance too.
It'll run well enough to play smoothly. Why not ask your cousin to install it and look how it runs? But for the most part should run fine
Not scamming you? Great deal IMO. had a 2200g back then (paired with 580) but will still be CPU bottleneck for csgo. Game likes to drop to 90 fps / stutter a bit in heavy gunfight, at least on 144hz. This is with slightly more than normal amount of chrome tabs open.
Also, make use of the process lasso trick to get more stable fps, you can search it or I can explain further/provide resources
The time I spent playing this game I could've been...
...applying for jobs
...making friends irl
...getting a gf
...spending time with my family
...becoming a better man in general
From the time I spent in this game, I got...
...an extremely racist and homophobic vocabulary
...free Russian lessons
...anger management issues
...borderline autistic tendencies
I think is decent for 200e
I'm not sure but I think it will go to 200fps
But if it is your cousin's pc, you can try how runs the game.
