You'll find improved voltage regulators and more consistent long-term overclocking on a superior board, but if you're already stable at 4.3 GHz, the extra cost isn't justified. You won't face restrictions in games at that speed. It's wiser to invest more in a graphics card rather than spending on a new motherboard or CPU just to try higher overclocks right now.
