even with an amazing laptop you may still experience lag due to the hardware requirements and bugs with the emulator. i have 2.2 quad core that overclocks to 2.9, 6 gb ram, nvidia geforce 450m video card and standard harddrive. ive tried any recommended settings for pcsx2 i could find even game specifics and very few would play full speed with ok resolution. instead im using a ps2 fat with free mcboot and esr and soon opl or hdloader
