Would an ssd help stop lagging in games

No one needs an SSD. sleep mode is faster startup. unless you open and close programs constantly, play games with lots of load time or have a laptop. Once something is in memory an SSD does no good, so with 8GB which is cheap you are usually fine. Just depends on how you use your machine.

Samsung 830 and crucial m4 are great though. If you want one get at least 128GB.

Here's a good deal.
