my geforce 4 ti 4600 is now almost 3 years old. im still able to play most of the games at decent resolutions. But few games really seems to struggle at some points of the game( irrespective of the resolutions i played). It has got shader 1.0 support. is that the problem for its low performance in recent games? I went for an upgradation last year replacing ti 4600 with 5600 xt, quite disappointed with its performance and returned it back. Now should i upgrade my agp card so that i can get better performance in latest/upcoming games. will cards like 6200,6600 offer better performance than 5600 xt. is the new upgrade is recommened or should i wait for some more time?
