No worries bud. Although ivybridge isn't going to be a massive leap in CPU performance it will have a much better integrated graphic processor (IGP).
Now for gaming you will use the dedicated GPU obviously but there is something called quicksync which allows software to use that "dormant" IGP to "turbo boost" encoding of movies. It makes a big difference on sandybridge so ivybridge should see even better results.
Oh I should also mention that many mobos state they have a PCI-Express 3 slot for your GPU but you need an Ivybridge CPU to make use of it
