I at least want a 4.0GHZ CPU . My case is white and black so The powercolor wont look so good in my case. XFX looks better.
If you care about the looks more than the performance then i cannot help you, the 7870 xfx is a LOT slower than the 7870 XT. And i don't get your part about the 4.0 ghz, you do realise the 6300 is better right?
