I'm not entirely sure because of the wording, but is that a 6 core processor on the Paladin? Because that's overkill for most gaming, combined with that graphics card and 16gb ram you should be able to run everything smooth at max settings before overclocking. Heck, it's overkill for most rendering too.
If price ain't an issue, I'd get the Paladin. iBUYPOWER is a pretty reliable brand, their products are pretty damn good for price.
