[Vanquish]

Edit : btw vanquish 270x is an oc'ed 7870..

Nah it's different for reasons other than the core clock speed. it uses entirely different architecture (270x is using Curacao XT + 7870 is using Tahiti). Also I think the memory speed, bandwidth and shader units are different. But yeah, they are similar.

I don't get how people can use an i5 and a 270x on a 450w PSU. it seems like you just made that up, since the 270x uses almost 200 watts of energy on its own, most i5's use about 120 watts on load (can be more if you have newer architecture or if you OC).

Based on the specs from Felix's PC I would guess that he doesn't have a 500w+ PSU installed so a 270x is a stupid option.
