Yer the banshee was sort of the Voodoo 2.5, it was originally bought out to compete with the TNT, but then nVidia forced 3dfx into releasing the "Avenger" core GPU (Voodoo3) because they released the TNT2, which kinda delayed both the "Napalm" (Voodoo 4 and 5 VSA 100 and never released VSA101 chips) and ultimately the delay of the "Rampage" core which proved to be one of the nails in the 3dfx coffin.
3dfx days were great, ah Glide was so perfect, and 4x FSAA in 1999 was extraordinary. SLI on the Voodoo2 in 1997 lol! Then again on the Voodoo5.
And to think nVidia and ATi are only just realising the potential of SLi (ATi's feeble attempt at AFR, a similar technology, on the Rage Fury Maxx was just pathetic lmao).
I dunno if the Banshee would be powerful enough for the Glide game I need to play lol, I will have a read on the net and see, the game was developed for the Voodoo3, but with the 4/5 in mind, so it might just about be good enough since the 3 was heavily based on the Banshee core.
Ill get back to you on it hehe! Thanks anywayz matey!
