Not really TBH especially at that size, it just makes the graphics card work harder.
There may be a lot of 2ms monitors, but the difference between one of them and an 8ms one is imperceptible, a lot of it is just marketing to cover up what is usually a rather basic TN screen (same with the "dynamic contrast ratio"). Personally, i'd go with
this screen as it is considered the best 22in around. This is because it is fast enough and it uses a brilliant e-IPS panel - so all competitors pale in comparison to it's image quality and viewing angles.
