well , i had the same problem . so 8 months back bought a 128mb 5200fx 4 bout 7 k . no the price is high n at that time the agp version of the same card was 4 bout 4.5 k , but i bought a PCI card .
at that time only those shitty mx440z were available 4 the pci slot , so had 2 import it thru a dealer in nehru place .
so what i think is that if u dont buy an agp mobo , n still wannna get a gfx card , reckon u would have 2 do what i had 2 .
btw , m gonna buy a new rig in may . so if u want , u can have the 5200fx card i got , is in a gud condition
