Question about PCI Express X16 and Video Card

Hey guys,I recently got myself a new gaming rig.

Mobo is an Asus P8P67-M (uATX) wich has:
1x PCIe 2.0 X16
1x PCIe 2.0 X16 (running @ 4x)
1x PCIe 2.0 x1
1x PCIe x1

and my VGA is a HD6970 (PCIe 2.0 x16)

The thing is I screwed up and connected the VGA in the slot that runs @ 4x speed and didn't notice until today.

So far I can play everything I throw at it,but I dont know if somehow the card is running slower while connected to that slot;is there really a performance increase if I connect it to the standard X16 slot? Is it bad for the card itself to be in the 4x slot?

Nothing bad for the card, but it cannot utilize the full bandwidth of a 16x slot if and when required in certain games.

Yes, you have severely limited your video bandwidth by using the X4 slot. You will not damage your card by using that slot. Whether or not you notice a performance increase will depend on the games and resolution you run them at.

I'd move the GPU to the correct PCIe x16 slot, as far as a MASSIVE difference nope not really, it depends on the Game, Crysis x16 vs x4 2~6 FPS depending upon the settings other games maybe 20~40+FPS but in those cases where you're getting 60+FPS vs 100+FPS. Anything above 60 FPS is lost to the monitor's refresh rate which is typically 60Hz or {60FPS}.
