Good enough to 5-box?

I recently acquired a mates gaming computer when he went back to school, and I think aside from the GPU it's capable of 5 boxing. I haven't really been boxing at all since early Wrath / late TBC. Anyway, here are the specs and a DxDiag.

GPU: ATI 7870
CPU: AMD FX 6300 6 Core
RAM: 16GB
SSD: Corsaire 128GB

Not sure if you need to know anything else, but I think the DxDiag will cover it.

You can open up 5 WoW windows and just see how it performs, dont even need to log into 4 and play on just one.

You could also create 5 trial accounts and 5-box to level 20 for free to test it.

That's actually a great idea, thank you.
