x4-880k is perhaps 10% stronger.
I doubt that would be worth it.
Best to start over with intel or ryzen.
$250 will buy you a G4600, lga1151 motherboard and 8gb of ddr4 ram which will be a better gamer and some 35% stronger single thread performance which is what most games want.
Don't buy fm2 cpu, they are all extremely outdated and weak by today's standards. Save up money and get an i3 8100, you will notice a big performance difference
You already have one of the best and changing for a little better one will result in almost no performance gain a a good amount of money wasted better invested in a newer platform.
