Hi, i have a hd 7770 and currently using amd a6 5400k and fm2a75pro4m motherboard but i'm selling cpu and mobo as the cpu is bottlenecking my gpu and i'm wondering what would be better, an i3 4130 or fx 6300 or i could try and save up (i'm on a tight budget) for the i5 4440 or something. Thoughts? and also what motherboard would you recommend with one $250 budget may be able to stretch to $300 but i would prefer under $300
