Okay, I got some prices from an online store here in Australia:
ATI Radeon 8500 64mb DDR AGP OEM Pack
$562 (RRP $699)
Hercules 3D Prophet III Titanium 200 AGP
$480 (RRP $554)
Leadtek WinFast GeForce 3 Titanium 200 TDH 64mb DDR TV & DVI
$531 (RRP $600)
Now, judging from that the Radeon is only about $30 extra than what I was going to pay for the Leadtek - is the Radeon 8500 really THAT much better?
