I have the following: IE 7.0.5, 2.8GHz Pent with 3GB RAM and cable Internet speed. I pulled up the site and my browser locked up. I launched it again and decided to just let it run. It took 1 min 15 secs to load the main page. Browsing other pages took less time but still should a significant lag. Hope this info helps. Cool new features though and I look forward the BETA.
