Yup, If you remember (and I know you do) I purchased the Zotac 680 a few months back. The week I had to purchase was the week every shop in the UK was out of stock (literally) except OCUK who had a few brands. Zotac was the only brand with 5 years (EVGA was out of stock). So I was forced to purchase the Zotac. I know some of you bought multiple 680's for SLI. I purchased an EK full cover waterblock and it's been running on water ever since with temps halved. I must say I'm really impressed with the performance boost when overclocking. I know some will get better OC but I get 200mhz on GPU core and 500mhz on vram. I realised how important it is to use the artifact tester that comes with EVGA precision since I can get the ram to 600mhz but if I go above 500mhz there are artifacts. I like my overclocks artifact free. With this OC I get quite a significant FPS boost in games which is crucial for me especially since many games I play with 3d glasses. Once in a while I get the red screen crash when speedfan starts. Some others get it too and it can be a problem but for me it only comes once in a while when speedfan loads and accesses the GPU. When the red screen comes invariably have to press the shutdown button and boot the computer again. If it happened on a daily basis I'd be angry but since it's maybe once in 2 weeks it's no real problem. What do you think of your 680/s?
Think its quite good, I have to admit to being disappointed initially after spunking 500quid on the thing with associated cooler as it couldn't max everything to the level I wanted at stock, but I'm over that now and actually it clocks lovely +200 +600, everything is pretty smooth much better than I have ever had, and part of my issue is that I also moved from 1920x1200 to 2560x1440 at a similar time which obviously needs the grunt, so the leap doesn't feel as much as it might of if I stayed at 1920.
I am limited to 1080 cos of the 3d monitor. The 680 is the first GPU I had where the overclock is so big it really makes a difference. On air it was quieter than my previous MSI 560Ti but overclocked was not good for air. Adding the waterblock didn't increase my overclock as such but it means I can OC without the heat and fan noise. Wish the voltage could be unlocked. Some games I could barely run on my 560Ti SLI... Hard Reset for example but the 680 rips through it even in stereoscopic 3d.
