That phone has a very old SOC (chipset), the MTK6580. That is about 3 years old.
And keep in mind, when it says 8GB ROM, that is the entire internal memory: take out some for System, Boot, Recovery (etc) partitions, and you end up with (maybe) 1.5GB for Data (apps). Which is not that big of a problem, if you're planning to Root and change the mount path (for Data) to external DS Card.
