You could go for a 8500 or 8600 but the improvement wouldnt be dramatic and finding those chips at a cheap price would be tough
Since you are upgrading your PSU I would sell off the 7750 and use that money plus what you planned for the CPU to upgrade the video card to a higher level since gaming really needs more of a video card
I would lean towards a AMD video card mainly because generally they require less wattage
I hope this helps
