try connecting the monitor to the motherboard output (if it has one) 
try a different cable
 

Lol, it's okay. I'm no one of consequence. And a RAM part number isn't going to affect anything. I mean, you live over 5000 miles away from me.
I basically want to see if I can find a way to get you a RAM upgrade from where you are at a very cheap price tag. I'm looking into it. Looks like around here the price of 16GB of that RAM is only around $12.00 to $16.00. It's how you will get it is the next finding.

HAPPY NEW YEAR 

What's the part number? M471B5273DH0-CK0? M378B5273EB0-CK0? Has to be specific. And you currently have 2 sticks of 4GB right?

i never say it will perform badly.

Because photoshop and premiere don't really use your GPU so performance is solely depend on your CPU power, hence CPU bottleneck. 

I don't think you going to get CPU bottleneck in Fornite unless you aiming for like 150-300 FPS.
Not sure about Minecraft, should've no problem for 60fps. 
CSGO can be a problem if you aiming high (200-300) fps i think.
 
Photoshop/Premiere is 99.9% CPU bottleneck. 

You got an average buy. I'd say you paid just a tiny bit more than you could have. Nothing to pitch a fit over really.
i7-3770 - $50.00 to $90.00 USED GTX 970 - $60.00 to $80.00 USED 8GB DDR3 RAM - $12.00 to $22.00 USED That's around $122.00 to $192.00 for these 3 things, depending on their condition and brands of course. Pretty much around $100 to $150 will get you a case, power supply, motherboard and some type of storage. So that's around $222.00 to $342.00 that you could have built it yourself for. Again, depending on the brands and conditions of each of the actual parts you got.
Depends on the game you play. There's a bottleneck present somewhere in pretty much any PC. This combo is a good combo imo. Test some games and you can see any bottleneck for yourself. The 4GB of VRAM should limit the use of higher textures and certain VRAM intensive graphic settings being set to higher settings. This limit will mostly take place in newer graphic intensive games released over the past 4-6 years or so.
 
Just keep the textures and VRAM intensive graphic settings around Medium to High while monitoring your VRAM usage and it won't be much to worry about. Less graphic intensive games won't push your hardware to the extreme so not much to worry about with them except optimizing the game in general.

RAM, not Vram

I say get another 8gb of RAM and you will be set for most games.

So which game did you run into recently that needed more than 8GB system memory since you're seemingly hell bent on it being not enough? 

i just bought a pc for 300 $ with a gtx 970 , i7 3370 and 8 gb of ddr3 ram
did I do good buy ?
does it bottleneck with gtx 970 and i7 3770

i7 3370? 

The only "bottleneck" i see here is, only 8GB of RAM
