I'll be gaming at 1920x1080 and was wondering what the difference was between the Flex and Vapor x? I know the Flex is supposed to be easier for setting up multiple monitors but I don't plan on doing that....yet (possibly in the future) and that the Vapor x has better cooling but is also more expensive. Any suggestions on which route to go? Or feel free to suggest another card if you want. Will be buying all the parts for my rig next week.
