I use PJ64 and 1964 they both are fast 1964 being the fastest of the 2 and pj64 beign just beign realy, they both are great i use pj64 the most and only use 1964 for playing 1080 and 007 as they run better on 1964 for me. but go with what works best for you i mean some people use UltraHLE god is that old and is best for 3DFX cards not Geforce cards.
