since there is no Athlon x4 880 I will assume you meant Athlon X4 880K
1) looking at the CPU scores PassMark scores ref:
https://www.cpubenchmark.net/CPU_mega_page.html
The A10-7800 is not an improvement over the A8-7600, leaving the Athlon X4 series clearly a better CPU.
2) Looking at the CPU compatibility list on the MSi manufacturer web site:
https://www.msi.com/Motherboard/support/A68HM-E33-V2#support-cpu :
we see in the
Athlon series all the following compatible cpus: Athlon X4 Trinity model : 730, 740, 750K, 760K, 835, 845, 850, 860K, 870K, 880K
I checked with Game Debate web site and found identical info:
http://www.game-debate.com/motherboard/index.php?mot_id=3518&cpuList=MSI%20A68HM-E33%20V2
I checked with CPU-Upgrades :
http://www.cpu-upgrade.com/mb-MSI/A68HM-E33_V2.html and still found the confirming information from the Manufacturer. all lists are identical.
My suggestion, look in the PassMark rating system and find a cpu 880K or 870K perhaps that would solve your issue.
Below is the Athlon Listed from strongest to less.
