I have a dell XPS 8700 and i am aware of it not being particular the best gaming setup, but all my other specs are good, 3.6 GHz 8 gb of ram i7, but I am using a 720 GT card right now looking to upgrade. I am just afraid of it not being able to run the 750 ti sc, the one I'm looking at, because maybe of a small amount of watts my dell probably has. Any tips/suggestions would be great.
