Use AIDA64 or everest to monitor your 12v rail under load. Then post your results. Voltage before load, and after.... stress the cpu as well. On your power supply with your cpu, u could probably run 2 470s. The Core i7 is a power hungry monster and sucks down twice as much power as a core2quad overclocked the max. That's why i need a super powerful power supply to supply power to the cpu and gpu(s). This Kingwin pushes much more than 850W under load as well. i've seen 60amps+ load on the cpu and gpu. That's when the 12V line starts to drop big time. It's still worth a shot. Actually it would be a good test to run the 260 and the 470 so i can team up the CUDA cores for Xilisoft Video Converter ultimate. It loves cuda cores. The more the better. 448 on the 470 plus 192 on the 260 = 640 cuda cores! That should speed up my encoding tremendously! I compared my system to our Xeon Server machine at work. It takes 9 minutes to encode 3 videos to my HTC HD2 format using cuda and my 4ghz core i7. I did the same test at work on the server. It took 55 minutes using the Quad Core w/ Hyperthreading Xeon processor. Shows how much more powerful my system is than our Corporate server. They paid a fortune for that damn thing. It's loud, annoying and overpriced. It's an IBM server. The hard drives inside vibrate up against the case inside and make this god awful annoying vibration/ rattle. I'm constantly kicking it at work to shut it up. Again this is a $2,000 IBM Server machine which is 30 days old. What a piece of shit.
