I Know it really sucks
is there any hope for my pc?
Haswell may be 25% faster clock for clock, less in most applications, including games, Haswell will be more energy efficient, but not shockingly so, especially considering modern CPUs are pretty much very near idle 90% of the time. You'd be spending at least $300 on a Haswell CPU and the new motherboard it requires, in my opinion that's not worth it. If you are a gamer upgrade your GPU instead, if you're not a gamer then just hold on to the money.
