hi, i have been gaming playstation for quite awhile now and i want a new alternative for my ps3. i currently have an i7 computer with no graphics card. i am unsure if i should buy a nice graphics card for around $400 or buy a ps4. i am leaning towards the ps4 because ill be going to college in 2 years and that will be much easier and more fun to use in the dorm. any suggestions?
