For desktop charting/trading software: graphics use is relatively minimal: -the current bar extends up or down and changes color as it updates -indicators move and update -when a bar-period ends, the chart shifts one step to the left -L2 and other data are the only other moving images So only a small portion of the pixels on the screen need to be changed for the software. Compared to a movie or video where Every pixel on the screen changes whenever the camera-view is moved. Charts and data windows do not require any 3d rendering or anything intensive. So graphics should be easily handled by what?.. Possibly by any video card that was made within the last 10 years? (both integrated or dedicated) What about the CPU? For BASIC charting using a few indicators (no heavily-programmed strategy TradeStation), what CPU power and speed is needed.. -Will a dual-core or quad core CPU show any noticeable difference? -Will a 3gHz allow a smoother software display and function compared to a 2gHz? And the HDD or SSD.. For the running of software would a SSD allow the data to display any faster than a 7200 or 5400rpm HDD? (a SSD will open the software faster, but the question is about the operation once open) perspective-- In 1998, a Dell was used for terranova trading software, for a single 17" monitor. It had a 450-ish mHz CPU, a video card with about 12mb of memory and surely a speed of less than 200 mHz, and a 4500 or 5400rpm drive.
