Please hear me out guys. So i've had my Asus GTX 670 DCII (Non TOP) for 2 months now, and am experiencing several issues which lead me to believe that I have a partially defective GPU which is on its way out. These issues have been significantly exacerbated since my recent purchase of a larger monitor with a higher resolution for my main display, from 22" @ 1680 x 1050 to 24" 1920 x 1080, both of which I am running in dual-display now from my 670. Here are my hardware specs:
CPU: I7 3770K
GPU: As mentioned above and not overclocked.
RAM: 16GB Corsair Vengeance 1666
MOBO: Asus P8Z77 V-Pro
PSU: Corsair 850TX
OS: Windows 7 64-Bit
HD/SSD: 500 GB WD Caviar Black/180 GB Intel 520
Windows was reinstalled onto my new SSD at the same time I got all my new hardware and GPU, 2 months ago.
And here are the issues i've been having...
First it was Metro 2033 (Go figure right). I actually beat this game on my old GTX 275 on MAX in game settings with no issues aside from the occasional low FPS. Fast forward to when I had only my 22" display with the 670. I was able to play Metro for a while without any issues, and then one day when I ran the game the entire menu screen as well as in game was completely invaded by this blue hue which made it impossible to see anything unless I stood face to wall.
Then when I got my 24" monitor and tried to play on it, I still had the same issue, so I tweaked some game settings and started up again, and there were yellow and black artifacts trailing from all of the objects onscreen. It was like an 8-bit game on acid. When I restarted, the game worked!? Although at unacceptably low FPS.
Now, before I got the 24" monitor as my main screen to run in dual-display mode with my old 22", this was the only issue I had that I can recall. Now it's much worse. Gaming on my 24", Guild Wars 2 lags, Skyrim lags, -CRYSIS- with fraps runs at only 30FPS at best and dips below with only the the in-game settings maxed, no nvidia control panel settings enhanced. YOU'VE GOT TO BE KIDDING ME!? I have looked at -many- benchmarks for my GPU before I purchased it, so I have a very good idea of how capable GTX 670's are. They literally conquer 98% of games at full 1080 resolution. That is certainly not the case with my GPU, and it gets even better.
I decided to start benchmarking with the Unigine Heaven benchmark and compare my scores to others!
A buddy of mine has the exact same GPU as me, with the same monitor resolution. The only difference is his CPU is worse, an I5 2500K on a P8Z68 Mobo. Everything else is -identical-. His score was higher than mine. I built my girlfriend's rig just before I assembled my current rig setup. She has an EVGA GTX 670 FTW running on two of the same monitor I have for my main display. Her rig is identical with the exception that she has a weaker I7 2600K on a P8Z68 Mobo. Her lowest FPS on the benchmark was twice as high as mine, and her highest was 20-30 higher than mine. How can this be possible?
Just an hour ago I was playing Skyrim when suddenly bright and dark patches began to appear and flicker all over as if there was some kind of lighting issue. Shortly after the game -disappeared- back to desktop. No game freeze, no error message, no nvidia kernel driver stopped working notice like my old GTX 275 used to do. Just gone.
A $2000 rig and i'm getting this kind of performance? SOMETHING has to be defective in my setup, but I don't know how to go about dealing with it. I know Asus has lacking customer support, but with these issues hopefully I should be able to receive a replacement. It would be nice if my GPU would just full-blown bite the dust so I can be decisive...
