Hi guys, I currently have an XFX 5850 running. I want to get another card for xfire so kinda stuck. I can get another XFX 5850 for approx $170ish (approx exchange rate) or I could get an XFX 5870 for approx $250ish. Well I can go either way, so I guess I just need a nudge. Actually wanted to get the asus 5870 because it just looks so damn sexy. But it is a tad bit more expensive. Need help on this one, thanks in advance.
