My dad got me some parts for my Birthday to build a PC. After I built the PC I downloaded my games and got to playing. My games would crash and give the dreaded nvlddmkm driver error. After 5 days of hard testing I concluded that I had received a bad GPU. I have my Replacement GPU and games no longer crash. But one of the main games I tested on was Battlefield 4. In the Campaign I can play on High 1080p at 60fps. But with the Replacement card its really jumpy and is getting worse performance than the original. Its very confusing and im not sure what could cause this. At the time of writing this I am not at my dads house but I will be going there soon. I would like some advice as to how to fix this. I am going to try a new Monitor because we got a new monitor there and the one I was testing on is the one at my Moms house. If that doesn't fix it i plan to do a clean install of windows 7 and hopefully that will help. All suggestions are welcome :)

The GPU comes SuperClocked out of the box. Will this interfere with that?
 


No. Superclocked means it is already factory overclocked. Can you run Ultra at 60 fps?
 

With the first GPU I could play Multiplayer on Ultra at 60fps.

 


At 1080p? That is pushing it a little bit. One 270X can play at Ultra at 50 fps on most maps, and the 270X is better than the 660.

To fix the weird lag while remaining above 60fps. I was using the Double Molex to PCI Adapter and using just a straight PCI fixed that. As for the old Graphics card performing better than the replacement, I run can run games just like it could now. So I guess in a way it was a Power Problem but it wasnt the PSU. But thanks for all the suggestions.
