Not "not intended for games", but is intended for entry-level or casual games. You can play SA on medium settings with an 8400GS, but you need to have a better one if you want to play IV decently.
I read that A Intel GMA 4500MHD Is as good as a 8400GT, but that card sucks too XD
Then Can I play GTA 4 with the Intel GMA 4500MHD or not???????????????????????/
