Just bought myself a tachyon g9600pro 128mb and have upgraded from a Geforce 2 Pro 64mb.
Can't say I have noticed a significant increase in performance at all, infact some games seem worse off. Tribes 2 for example can't handle gradients very well on the ATi card but does it perfectly on my old GF2.
I remember hearing ages ago that it was a wise move to format your hd before going from an Nvidia card to an ATi card. Is there any truth behind this?
I'm hoping so otherwise I might have to opt for a revised 5600 Ultra when they show up.
Cheers,
Chris
