Hi everyone, I recently upgraded my GTX 550ti to the GTX 680.
I thought I would be getting better performance and all, but it seems
that i'm getting worse performance on games that my 550ti could play with ease.

maybe your motherboard has the problem on it..
i think your card is powerful to handle by your mobo, i mean. your motherboard
can't supply enought V to your card as a result it ddnt functioning well..
or try to contact the dealer, maybe theres a mulfunction in the card.
