I'm most interested in the graphics engine. I dont quite grip the shared memory aspect of it as it relates to games. i know what it does, that it isnt the best solution and why they have it but dont know if it is adequate. Its an Acer with SiSM760GX chipset with integrated Mirageâ„¢2 graphics, 3100 Sempron, 512 ram. What are you opinions on the graphics? Does adding more ram to shared memory type of system help at all? I could stick another 512 in there but I assume thats the best i could do. Mostly, the lappie is intened for some of the older games of the GR years. Doesnt even have to run but midrange type settings for display. Price of the laptop is 500 US. Thanks.......
