T500 owner here with (what at the time was quite expensive) on-board plus discrete graphic cards and 1600x1050 screen. After replacing the drive with SSD and upgrading to 6GB, it's working as good as when I bought it in 2009, even with Win10Pro on it. I wish the multiple replacement batteries I got for it over the years were as performant ;o)
