No better.
I-Ram card, 4 gig solid state drive. I put HZ on it... no improvements.
Mind you, I'm running a Quad core cpu and dual 8800 GTXs. Processing and graphics capabilities are way beyond what this game's designed to take advantage of.
Even with the game running on the card, I still sit and stare at a black screen at portals for up to 2 minutes, no mobs spawn, engaging a crafting machine can take a minute or two, etc.
