Another bottleneck in a PC is the speed of the storage. Maybe the hard drive is slow, or that it is filled up to the point where it is having an adverse effect on performance (if you've got less than 10 percent of your storage left, it's probably time to think about upgrading).
After RAM, upgrading storage is one of the easiest, cheapest, and best upgrades you can do.
If your PC currently uses a hard disk drive (HDD) for storage then you could give it an even bigger performance by swapping it out for a solid-state drive (SSD). These are pricier than regular HHDs, but the difference in transfer rates is like night and day.
If you're not sure what your PC or Mac can take, then once again I suggest you take a trip over to either Crucial or OWC, where you will find a wide selection of both HDDs and SSDs to choose from suited to your particular system. OWC has a great selection of high-performance drives, for both PCs and Macs, including the MacBook Air and the new Retina-display MacBook Pro systems.
If you know what your system takes, then visit your favorite retailer, where you will undoubtedly get a cheaper price, but you will be on your own if you make a mistake.
