Oct 30 Discreet or Integrated GPU I have a late 2012 iMac with a NVIDIA GeForce GT 640M 512 MB. WoW has worked great on this machine since I bought it in 2013 for $1030 with no tax (on a military post). Since BfA install/launch, it has slowed down considerably, and not just with the game. It has slowed down period. I thought about adding more RAM (I have 8GB), hearing that iMacs with integrated graphics share memory with the graphics. I looked into it and couldn't figure out how to tell if it had integrated graphics... the instructions I found specified to "look at the About This Mac settings." Well, all I see is the NVIDIA, but nothing indicating discreet or integrated... so after searching deeper, it "appears" that this is not integrated. Is this a proper assumption? Anyway, I really don't want to buy a new machine, but I may have to. I did find this on Craigslist, but I'm not sure if I want to bite. https://washingtondc.craigslist.org/nva/sys/d/apple-mac-pro-late-2013/6732953504.htmlRitchie4 Oct 30
On July 20, 2011, Apple released updates to the 11.6" and 13.3" models of the MacBook Air, which also became Apple's entry-level laptops due to lowered prices and the discontinuation of the white MacBook around the same time.[5] The mid-2011 MacBook Airs were powered by the new Sandy Bridge 1.6 or 1.7 GHz dual-core Intel Core i5, or 1.8 GHz dual-core Intel Core i7 processors, that came with an Intel HD Graphics 3000 processor, and with a backlit keyboard, two USB 2.0 ports, FaceTime camera, a standard of 2 GB of RAM (configurable up to 4 GB), Thunderbolt which shares function with Mini DisplayPort and Bluetooth was upgraded to v4.0.[36][37] Maximum SSD flash memory storage options were increased up to 256 GB. Both 11" and 13" models had an analog audio output/headphone minijack (that also supports an iPhone/iPod touch headset with microphone), but only the 13" model had an integrated SDXC-capable SD Card slot. These models use a less expensive "Eagle Ridge" Thunderbolt controller that provides two Thunderbolt channels (2 × 10 Gbit/s bidirectional), compared to the MacBook Pro which uses a "Light Ridge" controller that provides four Thunderbolt channels (4 × 10 Gbit/s bidirectional). A USB ethernet adapter was immediately available upon release and a Thunderbolt-to-Firewire 800 adapter became available in mid-year 2012.
