Questions about GTX 1080s

GentlemanOrange · Oct 9, 2016

Hey everyone! I'm just bought a graphics card for the computer I built over the summer
Specs:
CPU: Intel Core i7-6700K 4.0GHz Quad-Core Processor ($328.99 @ SuperBiiz)
CPU Cooler: Noctua NH-D14 65.0 CFM CPU Cooler ($70.88 @ OutletPC)
Motherboard: Gigabyte GA-H170-GAMING 3 ATX LGA1151 Motherboard ($103.98 @ Newegg)
Memory: Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-3200 Memory ($86.92 @ NCIX US)
Storage: Samsung 850 EVO-Series 250GB 2.5" Solid State Drive ($99.99 @ Dell Small Business)
Storage: Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive ($74.88 @ OutletPC)
Case: NZXT Phantom 410 (White) ATX Mid Tower Case ($87.99 @ SuperBiiz)
Power Supply: EVGA SuperNOVA NEX 650W 80+ Gold Certified Fully-Modular ATX Power Supply ($78.99 @ SuperBiiz)

I bought a Gigabyte GeForce GTX 1080 8GB G1 Gaming Video Card ($619.99 @ NCIX US). It should be here in a week or so. My questions are as follows:

1) Is my computer powerfully enough to eventually support SLI, or are there parts I will need to replace?

2) For now at least, I'll only be doing 1080p and later doing VR. How long do I have with this build before parts become poor for this?

Anyways, thank you everyone for all the help!

I think that the only tight thing there for the SLI is the PSU. Only 650W is really tight. 750W or 800W would be a bit on the safer side there.

you are so overkill for 1080p that you should not have to touch the system for a few years at least. even for vr really. sli would be such a waste for either use at this time but you will probably want more than your 650w psu. the g2 uses about 225w if i recall right running at full load. so 2 of them plus the rest of the system would be a bit much for 650w. you'd be at the high end of usage and that's not good even for a top quality unit to run near max for long periods.

It used to be that VR did not support SLI...I think that's still the case.

The highest end VR systems (vive and oculus) will work extremely well with your GTX1080 and PC - right through till the next VR headsets come out. I've no issues with my GTX980 and oculus (your 1080 is twice the horsepower of a 980). But note that manufacturers will always balance with mainstream PC systems and gtx hardware - you're not going to get twin 4k headsets anytime soon (as much as we'd like them), thus, I'm sure you'll get plenty VR mileage out of your new PC.

1. The I7-6700K is as good as it gets for gaming. You can not do better today.
But, a H170 motherboard is not capable of sli. You will need a Z170 based motherboard.
Worse, you can not overclock a H170 motherboard. Change to a Z170 motherboard regardless.

2. GTX1080 is overkill for 1080P. no problem there.
I would not be planning of sli if you think you need max graphics for VR or 4k gaming.
My plan would be to sell the GTX1080 in favor of a Titan X pascal.
It will still run on a good 650w psu.
Remember that some games will not support dual gpu and may actually run slower.
And, dual gpu may have issues involving screen tearing or stuttering.
OTOH, if you are looking more at VR, there may well be a superior implementation with dual cards.

If you may want sli GTX1080, buy a stronger 850w psu up front.
Overprovisioning is ok, a psu will only use the wattage demanded of it regardless of the max capability.

Ya man SLI is on its way out anyway, I just upgraded from sli'ing 2 GTX 760's to a GTX 1080 and I am never doing SLI again.

But ya you're soooo overkill for 1080p, if you have the monies you ought to get a 1440p IPS G-sync monitor.
