Hi all, new to the forum here. Seen this post thought I might be of some help.
I have tested and own all 3 video cards you make mention to plus the fx5600. A lil' info on these-
ti4600- most are 4x agp, none have dirx 9 support, very fast, less "eye candy" price varies from $229.00 to $279.00 w/rebates
fx5600- on par with the ti4600 not quite as fast, has agp 8x and dirx 9 support, 2 versions- 1) has 128 memory, 2) has 256 memory, about same price as 9500pro $179.00 @ best buy
9500pro- about same speed as the ti4600, has agp 8x and dirx 9 support bios flash can make this card perform close to that of a 9700 non pro. it's memory limits this generally less expensive than the ti4600 $199.00 @ best buy
9700pro- very fast most speed of all listed even with eye candy on full blast, best value for the money- does all of the above but much faster. renders beautifuly $299.00 @ best buy
as I personally own all 4 of these cards the one not in use at present is the fx5600 if that is any indicator of how I feel about their perspective diferances.
Hope this helps ya decide, as any of the above are good choices, just depends on what ya really want them to do.
