Hello!
I would like to upgrade my computer a bit but don't know where to start. I built this computer on my own back in February 2014 with some PC building guides on Youtube. I am wondering if I should buy a completely new build or upgrade this... I'll probably end up upgrading this computer a bit and then later buy a new one. My budget for upgrading is under 400 euros.

depending on your usage, you could update the graphics card for a quick improvement to gaming,otherwise you'll need to upgrade your cpu, motherboard and ram all together, with 400 euro budget it will be tight for all 4 items, but doable with the cpu/mb/ram

From my point of view, I would wait, save up and get a new graphics card and CPU/MOBO/RAM altogether.

You'lll be able to still play stuff in the time it takes to save for a full rebuild. Then the sytem you have will be more balanced eventually. I'd also suggest replacing the H100i with a new cpu cooler as it might be approaching the end of its working life.

You can keep all the other parts of your system if they are still working fine. Upgrade them as and when you need. Personally I like to replace my power supplies when they get towards end of warranty, but I'm guessing that Seasonic you have has a 10 year warranty? So its probably just fine.

If you absolutely must do something now get a GPU with the money and youll see an improvement at least. I wouldnt suggest updating your platform and sticking with the GTX 780, I highly doubt there would be much difference in most games.
