My quad core processor and 4GB of ram are not enought to overcome the fact that open source video drivers are terrible. I could not find a way to make Mint run smootly enough to be usable on my dual monitor setup. My system runs fine on XP, Vista and 7, but both on Ubuntu and Mint my Radeon X1250 makes the experience totally unusable. I will stick with Windows 7 for now as it run very smooth.
