Changing out the video cards on any Mac, with the exception of the Mac Pro, is next to impossible.
You can configure one of the new iMacs with a better video card but cannot buy one separately.
If your proposed system meets the game requirements, you should be OK. I have no idea what the system requirements are for this game.
You could always keep the PC for playing games on and use a KVM switch with your Mac Mini and PC.
hi guys, i've been a pc user my whole life looking to switch to mac. problem is that i really like to play counter strike source, and some other older pc games that i have. i know i can install windows xp to play these pc games, but i dont know much about mac hardware. what kind of hardware would i need to run counter strike source good? i was thinking about getting a refurbished dual core mac mini to make the switch the cheapest way possible, but it has integrated graphics. is there any way to put in a video card, or do i need a whole other mac?
