Is this possible
More aboutworth upgrading
it could be possible but your hardware could not keep up with the GPU. What is your PSU btw
Nope, don't do it.
You should buy an i5 2500k and THEN a 670, or both if you have the money.
And surely you need to buy a new PSU and a motherboard (it may be not compatible)...
