^ Yes, but simply having an arbitrary score in a synthetic benchmark without anything specific to compare it to is no reason to think there's something wrong with your PC. OS, hard drives, drivers installed, all the little things that people do to personalise their setup can change two PCs with identical hardware into different performers. Synthetic benchmarks are not a good measure of real-world performance. If I were getting crappy benchmark scores and could still play my games at high settings at good framerates it'd not be something to worry about.
@OP: You can't even see images refreshed faster than 60Hz so it's not like the 60Hz "cap" on LCDs is something that will affect your gaming experience.
