So I just completed the build of my new system. Still to do a lot of tweaking but have gone from average 14-15 FPS on flashpoints, was getting down to 8 on first boss in S&V, almost unplayable, all on lowest settings, to getting around 70FPS on highest settings.
The difference is unbelievable, like seeing the game for the first time, I feel like Neo in the Matrix, no more lag between pressing buttons and seeing action, everything draws immediately.
Can't wait to parse and see where I am, should be a big improvement.
