I've been looking at the laptops in my link, in particular the graphics cards, what with processor, memory etc all being similar, and all but one have Intel GMA 900 integrated graphics, which is what you would expect for machines that are meant for business use. Incidentally the one that does have dedicated graphics is the D810, which has a dedicated ATI RADEON X600 128MB chip, and by all accounts can run some great games on really good settings. But the sacrifice is made by the fact that it's much bigger and heavier. Anyway, the poor graphics on the other ones is demonstrated by the performance graphs at this link:

"With a score of 348, it is obvious that the D430 will not be playing the latest games. Sure, it will play Grand Theft Auto: Vice City, Final Fantasy VII & VIII, the original Neverwinter Nights, and maybe even the original Halo game. But anything that is not at least a few years old is going to choke this card. Halo is pushing it, as at the lowest settings it is barely playable, so I think I'll stick to Solitaire thank you very much."
Now surely if the D430 can run GTA Vice City and the like, it must be able to handle Rogue Survivor, Dwarf Fortress and the rest of the Roguelikes mustn't it?
