Upgrading your CPU would be great for you right now. Upgrading to 3600 directly improves your CPU speed by 12.5 %(6x3.6 GHz vs 6x3.2 GHz), RAM speed by 533 MHz(3200 MHz vs 2667 MHz), Cache memory by 16 MB(32 MB vs 16 MB), Turbo Clock speed by 0.6 GHz(4.2 GHz vs 3.6 GHz), Memory Bandwidth by 4.98 GB/s(47.68 GB/s vs 42.7 GB/s) and by another newer version of PCI Express(PCIe) ( 4 vs 3). And upgrading RAM would always be a cherry on the top. Hope this helps.
