I would rather get an xfx, but that heatsink on the powercolor looks like it would be awesome if i removed the shroud and let my 260cfm side panel (4X140mm fans ) cool it....

I trust xfx as a brand more, but their cards use a stock coolers, (Or at least one of them does the other one looks like a deformed version of the stock one . ) anyways these wont benefit from the tornado that is my case. Also both the xfx's look exactly the same spec-wise except for the weird coolers? I if were to go xfx which would be better?

Any quick advice before i pull ze trigga?

I actually have 3 copies of stalker, two of witch were pack-ins with gfx cards

So it basically comes down to a good brand/ warranty or a good cooler( assuming that the powercolor cooler is actually better, i think it would be with my massive airflow)

Also the shipping on the powercolor is free, but shipping on the xfx's is 8$ so they end up being the same price.
