Sorry Steve, but that is actually quite untrue. I have a HD4550 which should be right there between the 4350 and 5450. I play Guild Wars at 1920x1080 with 4xAA (Edge-Detect, 12 samples) and 16xAF, plus HQ AAA, and I maintain 45-60 fps at the highest quality settings. It drops down to 30 in heavy fights with lots of spells flying around (like sitting in the middle of a Meteor Shower) but it is still absolutely playable for a MMORPG. WoW and CS are significantly less detailed and should pose no difficulty to these cards, though I can't say for certain as I don't own either if these games.
