Ok I purchased both ISBoxer and PwnBoxer. I liked the way ISB auto targeted with the master and auto followed and such (using jamba) but PB runs smoother. I was running a system the was moderatly good but not awesome or anything. I decided to upgrade as I wanted to use ISB. My system now stands at:

i7 870
8G RAM
GTX 580 3G
120G SSD

Before upgrading I could only run 3 characters in Dal but I could run all 5 in places like Org with no real lag, though I did get lag pretty bad in some places. When I upgraded I expected to do better but now I get stuttery play while moving around Org and when I go to Dal, 1 of my characters just locks up the game. I tried removing and redoing ISB from scratch but no help. Right now I have made NO changes to the straight from the download config for ISB. Any ideas on what I need to do or what other info I need to provide. It just seems that with my system I should do better. If not I guess I'll have to figure out how to do all the scripting in PwnB ;o( At least with PwnB I can run all 5 toons in Dal smooth as silk.
