For my part, I would still take at least an I5 simply for the general performance.

In general, the computer is not bad, but as already mentioned, you won't get far with the graphics card. It also depends on what kind of games you play. The CPU isn't exactly top-notch either. You're better equipped with an i5. I wouldn't be too stingy with the mainboard either. I'd recommend getting a more expensive but better one, so that you'll still be in good hands in two years.
