I have been tweaking with my CPU this past weekend. It's usually pretty fast, but sometimes slows down with multiple charts/windows open. It's a pentium 4, XPpro with around 2.2GHz. The ram is only 126. How much would increasing to 256 help? Does it help just a little for trading or is it a big huge factor. I'm only average with computers and don't deal much with hardware. Thanks.
