Possible CPU bottlenecking my new GPU

I just recently replaced my GPU with an NVIDIA GTX 550ti. Now not only are my games to having lower fps than before, but just browsing the internet my mouse and fps are choppy. I am concluding that my CPU is not being able to handle the new GPU. My processor is an Intel Core2 duo at 1.86 and is about 5 years old. Is my CPU the problem here?

    Definitely! That processor isn't bottlenecking, it's literally blocking your gpu from doing anything! Upgrade your mother board to a lga1155 socket and get an i5 (2500k). it's really the only way for you to go at this point.
  2. Thanks for the quick response. So my only option is to replace both the motherboard and processor? (Basically they are both underpowering the GPU and out of date?)

    unfortunately, yes. Your motherboard isn't necessarily a direct problem, only that it doesn't support any newer processor, so if you want to upgrade your processor (which you have to), you have to upgrade you motherboard as well.
