Upgrade or New

[mikegale56]

Approximate Purchase Date: Next 1-2 months

Budget Range: ~$1,500

System Usage from Most to Least Important: Gaming

Are you buying a monitor: Maybe

Parts to Upgrade:
This was my build from 2013:

except I went with 16GB of RAM instead of 8.

I'm wondering if I can get away with upgrading the video card to a GTX 1080 and buying a big monitor with the budget rather than buying an entire new computer and using my old monitor. Will the power supply (600W) support the 1080? Will it fit in the case?
Alternately, I could build a new computer similar to the newest $1250 build and hold off on a new monitor. The one I'm using isn't bad, it's a 10-year-old 24" 1920 x 1200, but some of the new, larger panels would be cool if I could keep most of the parts in this current computer.
Thanks for any help!

Do you need to buy OS: IF new build, yes

Preferred Website(s) for Parts: Any

Location: Boston, MA

Parts Preferences: by brand or type Intel

Overclocking: No

SLI or Crossfire: No

Your Monitor Resolution: 1920x1200 or higher if I'm buying a monitor

And Most Importantly, Why Are You Upgrading: I typically build a new computer at the 3-4 year mark and it's been 3.5 years.

Just upgrade the GPU, maybe the monitor. The current generation of processors are not fast enough to justify the cost.

I would upgrade in a couple of steps.

1. Buy your new monitor.
Will it be 1440p or 4k?
Likely your GTX770 will run most games just fine.
And... keep your old monitor attached to the GTX770. It adds no load to gaming on the new monitor.

2. If performance is not what you want, decide if it is graphics limited or cpu limited.
I think it unlikely that a i5-4670 will be the limiting factor.
A i7-4790K might be your best upgrade if you are cpu limited.

3. CX600 does not have a great reputation for reliability, but should be no problem for most GTX1080.
I would avoid the highly overclocked versions though.
Actually, GTX1070 would be a very good upgrade for even 1440P.

I'll take a look at the power supply, thank you! I like your stepped approach, it'll save me from having to upgrade if I don't need to. Thanks for the help!
