Worth getting a new motherboard?

So my old z68 board died and I'm currently on my gigabyte h61 dv2 board again. I was thinking about getting a new (used) z68 or z77 board since I used to run my 2600k at 5.4ghz.
Before the board broke (brother broke a sata connector off didn't tell me shorted the board and it burned a couple of pieces).

The old board was a Gigabyte Z68AP-D3

The cheapest ones I can find are 100€
 


It's not my main pc but a secondary workstation which is more than powerfull enough for it. The only reason I would want a new motherboard is to speed up the cpu restriced test renders I do when working on it.

Any z68/z77 boards I have to avoid at all costs?
