So here's the dealio. I currently have an XFX 6870 and am looking into an upgrade. I've always found x870 cards to be good cards as I have owned a 4870, 5870, and 6870. So naturally I'm looking at the 7870. Given the recent price cuts they seem like they are at a good price/performance ratio. I'm willing to spend up to $239 for a 7870. So my question is should I go for the 7870 at $239 or pick up another 6870 for $100 less and pair it with my current 6870? Which setup would perform better? And is there another option for $239 or less? Right now I'm leaning toward the 6870 crossfire option as its cheaper and I'm already setup for crossfire as far as power supply, motherboard, etc. go but I would like yalls "professional" opinions first. Thanks ahead of time!
