Used CM GX II 550w PSU when I had R9 270X 2 GB.

Recently I got a new card alike but with 4 GB of VRAM. Is 550W sufficient now?

plenty. plenty of room. You could get a 280 or even a 280x and still have enough power and room.

You aren't overclocking your CPU and you don't have 10 HDDs so nothing to worry about. however, if your description is right you have a 1366x768 monitor. Why? You should get at minimum 1920x1080 since your system is built for it.

More VRAM with the same GPU makes no difference to the PSU requirement.

When I purchased this build, it went out of my budget limit and so I was hindered with a simple screen lol.

I just wanna make sure if VRAM plays a role in it.

The VRAM 2 vs 4GB won't make an impact on power. You really don't need a 4GB version. The 2GB would have been performed the same. People that buy 4+GB VRAM GPUs do so cuz they will play on 3 monitors.

But I feel doubtful on this fact. Games like Watch Dogs needed 3 GB of VRAM to run ultra textures. After I've got 4, I'm able to touch the highest point of the settings.

Also, I know that there will be no increase of frames per second but issues like stuttering and lags are vanished when using a 4gb one.

Yes, Watch Dogs with texturing does need at least 3GB VRAM. 4GB is ideal for it. You made the right choice getting a 4GB version. Most other games don't require this. Most games just need 2GB VRAM to handle fine.

I followed my intuition in here. There might be a chance that the next-gen games developed by Ubisoft, Activision, etc might need a good amount of virtual RAM for graphics to set everything at high/ultra.
