I was thinking of starting to mine LiteCoins with my current pc. And i was thinking if my rig would handle it?

This is my parts:

Cpu: Amd Athlon II 255 3.1GHz (OC to 3.7GHz) (47C at full load)
Ram: 4GB DDR3
Gpu: MSI R9 270 Gaming 2GB 955MHz (OC to 1050MHz) (65-75C at full load)
PSU: 450W (dont know the brand)
OS: Windows 8.1 64bit

I know that my cpu is garbage but i dont have enough money to upgrade it.

Will this rig be good for LiteCoin mining? And if so, How much LiteCoins could i expect out of 6-8 hours of daily mining?
