So I just got my iMac, it's not brand new but what I didn't know was how much the graphics card would effect my gaming experience. To give you a more accurate picture, here are my stats: Processor 2.8GHz Intel Core 2 Duo Memory 8GB DDR2 SDRAM Hard Drive 1TB Serial ATA 7200 rpm Graphics ATI Radeon HD 2600 PRO with 256MB of GDDR3 memory Operating system Mac OS X 10.6, Snow Leopard I'm not familiar with iMacs in general and I was wondering if anyone could tell me if indeed my problem with game play being SUPER SUPER choppy is due to my graphics card? I tried to play everything on super low settings and it was still just terrible. I've read other threads where people have had no problems playing the game with ATI Radeon 2600.. I wonder why mine is being this way. Please let me know, I greatly appreciate it.
