Is the price difference justified? I'm upgrading from a Ti4200, so I keep my hardware around for a while... The new vid card will be paired up with an A64 3400. I'm not gonna play Doom3 or HL2 because I'm not into those types of games, but I will play Tribes Vengeance and whatever else happens to come out that interests me (space/flight sims, RTSs, racers). Right now I'm playing IL-2: FB and it runs at about 10fps at parts, which is annoying...
