Heya, got my eyes on a 6800 Ultra DDL for my PowerMac7,3 (DP 2GHz) that currently has a Radeon 9800 XT. The 6800 going for $50, but I also see a X800 XT for $100. What's the better deal? Would either make at least 720p bearable? My main monitor is 2560x1440 so I really need a Dual-Link capable card. The G5 wont be used for gaming. I'm just trying to get it up and running again/Beef it up.
