"FSAA is decent at 2x, 4X is ok for older games."
Actually, I use 4xFSAA on quite a few newer games.  Madden 2001 and NHL 2000 quickly come to mind.
If you are into sports games, RTS games, RPG's, Flight sims... You'll use 4xFSAA.  
Personally, I can't live without FSAA.  I'm spoiled.  I started a game of NFS5, the other day, and forgot to enable FSAA.  I couldn't even get myself to finish one track, without going back and enabling it.
IamDavid, if you didn't notice a difference between a V3 and a V5, then you are most certainly doing something wrong.
Eug, UT runs and looks a lot better on my V5.  Benchmarks (especially with UT) suck.  And besides, AnandTech uses D3D instead of Glide for all it's UT benchmarks, which I still think is kinda screwy.  
Also that one particular benchmark shows a 
.8 fps advantage for the V3.  Hell, somebody coulda sneezed at the wrong time, to show a .8 fps difference.
