Wait for the price of the 1080ti to drop in the used market when the RTX3k series cards come out?

The only way I know how to future proof is to build your PC for the applications and quality you want now and then don’t change how you use it.

A video card is powered only with 3.3v (up to 10 watts) and 12v (in theory up to 65w from slot) and 12v from pci-e slots. 
5v should not be affected by video card.
 
My advice would be to buy a digital multimeter, even the crap 2-3$ ones would be fine for some basic tests. It's a very useful tool to have around the house.
 

You can unplug all cables of the power supply (the 24pin, the 8 pin from cpu, the sata/molex to drives, the video card)
You can force the power supply to start by connecting a wire between two pins in the 24 pin connector ... connect a wire between PS_ON (green in picture) and any GROUND pin
Now psu is started, so you can put your multimeter in DC mode (20v or higher if you have to set range manually) and put one probe (black usually) in any ground pin, and the other on the other pins. Put on any yellow pins to measure 12v (should get 11.7..12.3v) , red ones should give you 5v +/-5% , orange ones should measure 3.3v +/- 0.1v
The 5vSB is important (5v standby)... it should be 4.8v..5.3v ... if it's less than that, then that could explain system not starting... 5vSB is used by chipset to initialize motherboard and everything.
 
You can also gradually connect the components... for example connect just motherboard and cpu (24pin and 8 pin).
Leave the video card disconnected.
Connect the multimeter probes to a molex connector (ground and red wires in molex are ground and 5v).
See if the voltage is still less than around 4.8v when you start the pc just with motherboard and cpu connected.
If it's all good, add video card and see again.
It may be that something on the motherboard shorted out and consumes a lot of power from 5v, which forces the power supply to lower the voltage on 5v (because it's not capable of producing so much power on 5v)
It could also be your hard drive or something else that's shorted and preventing power supply from starting though it's less likely.
 

or you could wait till we have more intel on the intel GPUs? eh?
 

heres an ancient one worth a gander ?  So many sweet screenshots above, I enjoyed NFSMW (latter version)  great driving experience.
 

Was flipping trough some old backup files and came across screenshots from Battlefield 2142.
Actually does not look half bad considering it's from 2006.

LOL.. Did not catch that pic for some reason..
I had the E8400 @ 3Ghz so I would call this sys with the E7300 good for entertainment and internet browsing on your TV. How high video quality this system would manage will reflect a bit on what graphics card you put in it.
But I would not spend allot of cash to get this up and running because even a E84-8500 with mem and motherboard can be bought very cheap used.
I see allot off these systems with LGA775 E8400, memory and motherboard selling for as low as $50 up to around $102.

OK people.. I did the "put both drives in my main rig and HDD clone" and it was a complete success.
Thanks for your input guys

@CoolKD
I know that Acronis does a very superb job for backups and drive cloning. I don't know if there's a free test version of it though. The data transmission in your PC should work anyways. In case something goes wrong you could wipe your new drive and repeat the cloning in a different way. I mean your old drive won't be gone, so what could go wrong?

as long as your main rigs boot sequence is set to boot an the drive with the main rigs OS you shouldn't run into any issues with that regard.
 
 
 
For copying your OS try making a batch file with the following in it
 
xcopy “C:\” “G:\” /d /s /e /c /i /h /r /k /o /y /f
 
run as admin and obviously change the drive letters first to the correct ones.
