Currently I have an HP 9407nr with NVIDIA Go6150 graphics. My OS is Vista Home 32 bit, 2 GB operating RAM with 3 GB installed. 120 GB hardrive. My usage is basic web browsing, video streaming, AutoCAD usage (limited for class) and Office products. Vista is driving me nuts. I have thought about upgrading to Windows 7. I am also looking at the Lenovo IdeaPad Z570 with i7 processor, Windows 7 64 bit, HD 300 GPU for $699.
Any recommendations would be helpful.
