i play @ 1440x900 , i am planning to get a new GFX (HD 6870 without replacing my PSU),i don't want to get a 24" or 23" monitor because their resolution is (1920 x 1080) and it will cause a huge hit in fps,so my only option is a 22" LCD @ (1680x1050) or stay on my 19",so what do you think ?? , is replacing my monitor from 19" to 22" would be a significant change or not????
