    I have a MSI 890fxa gd65 mobo, 8gb 1600mhz ram, Phenom II 1100t x6, Galaxy GTX 780 HOF.

    First thing, throttling.. I spent the whole night dealing with this and it has been extremely frustrating. First I noticed through HWInfo64 that the card was throttling from 1000mhz down to between 5 to 600mhz or so during gaming, but temps didn't go past 60c during that time. Other software confirmed temps weren't going very high but it was still throttling. GPUZ looked like a damn comb for the gpu clock monitoring because it kept going up and way down constantly every couple of seconds or so. I downloaded a few things to try and get around this like NVidia inspector, the software that came with the card, gpuz, etc.. The only way I could get it to stay up on speed is to hit the damn turbo button on the back of the card itself. Hovered at 75 to 80c with 3200rpm fans which of course added some volume.. Why can't I just disable throttling altogether? I never had this issue with my GTX 580.

    The other issue is the performance. To be quite honest I'm slightly disappointed. I definitely get better frame rates than my 580 overall, but it isn't phenomenal. I also get some ever so slight stuttering. Not sharp stuttering, just slightly fast-slower-fast-slower stuttering every few seconds. Happens in Crysis 3 and GTA4. Haven't tested other games yet.

    My GTX 580 just worked. I installed it, always got consistent framerates and as far as I could tell visually, it never throttled. I can visually see it clearly with my 780. Any advice would be greatly appreciated. This HOF edition card is supposed to be faster than a GTX Titan. I've never bought an OC'd card before and never OC'd my 580 so I don't know if that has something to do with my issues or not. I'm a little disappointed at the moment and hope I can figure out how to get this thing running consistently fast and smooth. Maybe my old CPU and MOBO are holding things back.

    Probably your PSU is dying.From review "Otherwise, you're only going to see the performance of a typical 450W PSU. So if you only plan on having one hard drive and an optical, you might want to keep your video card choices limited to a pair of Nvidia 6x cards or ATI x1800 cards. If you're looking for something with power factor correction and decent efficiency, you're not going to find it here. But if you like the mirror finish of the X-Finity housing and the UV reactive FlexForce cables, this is probably the nicest lookng 600W power supply you're going to find."

    I have a similar problem, however I was getting massive stutter at 60 fps with vsync locked. I tried everything frame rate limiters, 3rd party vsync, overclocking. I put in a radeon card and everything was smooth so I figured i was missing something. I went into nvidia inspector and my maxium pre-rendered frames was to low. For instance in Tomb Raider If I leave it at 1 or application controlled I get massive hitching stuttering when panning the camera. When I set it to 3 or higher its perfect smooth, practically 99.999 percent stutter free. For some reason on my system the lower the pre-rendered frames I make it the worse stutter I get.

    Well that is very interesting because I tested out Far Cry 3 for a few minutes last night and noticed massive stuttering at 1 prerendered frame, and 2 cleared a lot of it up. I will try 3 tonight in the game settings. Is there an option for this in Nvidia panel? I can't remember.

    OP get rid of that PSU before it takes your whole PC out with it. That PSU is only 450W on the 12v rail. ULTRA is :puke2:

    please do not tell me you still have that ultra psu with a 780. that cpu is going to bottleneck that 780 pretty good
