If you needed a cheapish monitor for gaming...

Well that's not much of a decision considering the CRT is smaller than the LCD. Keep in mind that the dimensions of a CRT include the border around the screen, while the LCD dimensions are only the actual screen ("viewable area"). Now, if you had put a 19" CRT flatscreen in there, then I might give the CRT consideration; CRTs are still superior when it comes to fast motion in games, but you have to judge for yourself whether you can tell.

You could always consider a much less expensive used CRT in your area from http://geo.craigslist.org/iso/gb
I'd recommend a Sony Trinitron or NEC Diamondtron monitor 19" or higher.

Alright thanks but i still find it abit confusing, things like the refresh rates for example i understand when you play games for FPS is limited by the refresh rate of your monitor, but i know turning V sync off stops the FPS from being the same as the refresh rates so your fps is generaly say 100 so are things like refresh rates really that vital if there over say 60 on a LCD and 70 on a CRT, i know that question is a bit random but im just curious.
