GTX 460 Overclocking

Am I able to up it any more? What do you recommend? I can't up the core clock anymore though mainly because of it crashes when it goes past 880.

I recommend that you don't go any higher. A nearly 16% OC is pretty respectable. Also, if it's crashing beyond 880, that should tell you something. "It doesn't like going any higher."

You could fiddle with the voltages and raise the clock speed a little higher, but then you're looking at heat dissipation issues, because more voltage equals more heat, and you only have a single fan on that card (I believe). Is it worth possibly damaging the card? Or is this just a challenge to see how high you can go? If it's your primary card, I wouldn't push it too hard. Don't OC what you can't afford to replace.

Also, OCing can be fickle. All graphics cards and CPUs are not created equally. A high overclock on one card may be impossible on another.

Also, I think I would recommend that you not buy a CX series Corsair supply. It's sort of their low end.
They make better models in their TX and RX series. Other brands such as EVGA, and Seasonic are also worth a look.

Your spec show a Nvidia GeForce GTX 860. Did you change your video card or is this a different computer?
