Will this Pc be good for gaming?

Hi, look I think the first computer would run the game smoothly on low settings, the 2nd one on base price would run it smoothly in high settings. There will be games you won't be able to run with any of those computers. The 2nd one is your best choice of course, you don't really need any upgrade if you wanna run games like starcraft 2, total war shogun 2 etc. on mid-high settings. I'd say you go with it if you want to.
