Got my new GTX 970 not too long ago and the performance has been great at 1080p running everything at over 60 FPS no problem. But with lots of sales on 1440p monitors, I thought I might go upgrade from my old monitor to that but the GTX 970 is king for 1080p and I might need some extra power to step up to 1440p. That's where you guys come in to help me out with OC'ing so I don't fuck up and lose my warranty. My specs are:

CPU: i5 4690k @3.5 GHZ
GPU: EVGA GTX 970 SSC ACX 2.0
Motherboard: MSI ATX DDR3 2600 LGA 1150 Motherboards Z97-G45 GAMING

I would do it myself, but hopefully somebody with similar specs can tell me what they've got their rig OC'ed at so I can base it on my own

Again, thanks in advance for the help, this community has always helped me with whatever I needed help with and I appreciate it.

Cheers!

Hey dude,

Download MSI afterburner or something for your overclocking. Works a fuckin' treat.

Start off by upping the clocks without touching the voltage, in increments of 15 mhZ for your core. If you don't touch the voltage, you can't fry the card. Run a program like Unigen Heaven to check frame rate boosts / scan for artifacts etc.

Once you reach a point where you can't up the clocks without inducing artifacts, bump the volts up by 5 or 10 and keep going. Your card should have a limit set on voltage, it is extremely difficult to fry modern GPU's without tampering with the bios because of how effective their security mechanisms are.

Anything you change through afterburner wont fry your card so no need to be afraid of that, the max voltage it allows is not a lot. Evga is also really good about overclocking and changing bios and changing coolers and still honoring warranty so you're good there.

Do what toscar said and after you get everything stable, you can go into nvidia control panel and check all the boxes for dsr factors and then you can run some tests at 1440P. Just change the resolution in game to 2560x1440 and it will render at 1440p so the fps numbers and such will be almost exactly the same as they would if you had the monitor hooked up so you can get an idea of how it will perform.

EDIT: You'll notice even on a 1080P monitor that you wont need as much AA and such as you would at true 1080P so make sure to turn it down because it affects performance quite a bit.
