Which Pentium? Getting the newest hyperthreaded one will help you get the most out of your 980. No matter which one you get, though, you'll see a little bit of CPU bottlenecking that prevents your GPU from working at 100%. That's because the CPU can't deliver information to the GPU as fast as the GPU can process it, but it won't be a huge problem. Faced with a choice between a fast CPU and a fast GPU for a gaming machine, getting the fast GPU is the better choice as long as the CPU is at least fast enough to feed the GPU in most cases (i.e. don't get any CPU that's much older than the GPU). Worst case is that the CPU will hold you over until you can afford to upgrade your CPU. That will in turn hold you over until you can afford to upgrade your GPU, and so on. In the meantime, you'll have a decent gaming machine that will run most games. Ejoy!
