It will greatly depend on what if anything was slowing it down. If you were having a hardware not software issue like memory errors, cpu and other device temps climbing, or even a failing supply updating drivers alone won't really help that much. With memory errors however it can readily be drivers as well as bad dimms causing errors. The difference will be the errors seen. If you are into serious gaming then running a good diagnostic lke memtest every so often is a good idea especially if you start having problems.
