Hey guys, I know bugger all about graphics cards. This is where you come in. Im tossing up a few options for my next computer. Im a photographer, and need a Mac. But without shelling out for a Mac Pro, the graphics cards in them seem sub par. I need it to be good for photoshop, video, and graphics intense programs, but it would be pretty awesome if I could run a decent game on it. So... 1. Anyone got any experience playing PC games on a REAL Mac (using windows)? Was it *****? 2. The new iMac (when maxed out) has a 4gb Nvidia Graphics card. (http://www.geforce.com/hardware/notebook-gpus/geforce-gtx-780m). Or without upgrading it has a 2gb version. Both are GDDR5. How will they go games wise? 3. Weirdly, both of those chips are for mobile. Why are they in an iMac? And whats the difference between the card above, and the desktop version: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-780 4. If I was buying a new MacBook Pro (Laptop), the top version appears to come with both Intel HD 4000, AND an NVIDIA GeForce GT 650M card (1gb gddr5.) Why both? And is 1gb a big jump from my current laptop (intel graphics only). And for the Gamers out there... 5. If you were building a decent gaming rig, how big would your graphics card be? Any other considerations? 6. Anyone have any experience building a Hackintosh? (A PC, running Mac OSX, but able to boot Windows). How did it go? Did it run OSX well? Did it run windows and games well? Cheers!
