When I'm playing 12+ tables and running PT4, TableNinja, Sharkscope HUD, and the internet my computer starts to get slow. I noticed in the task manager that it would hit 100% of the CPU usage (I attached a screenshot of when I was grinding). There are a bunch of chrome.exe processes going on there. Shutting down the web browser helps but still isn't great. I got rid of as many applications on my computer that I could find that I didn't think I was using. My computer is a 2009 Asus with 4 GB of RAM and an AMD Athlon II X2 220 Processor (2.8 GHz); 64 bit.
Is there something I can do to increase it's performance? I've heard people talk about adding a SSD? I'm willing to buy a new computer if that will be the best. I would just need some advice on that then. Thanks in advance!
