iMac Question

[MiRai]

Stopped playing 9+ months ago.
Recently purchased an iMac for other stuff.
How well will this run WoW and multiple windows?
Using Parallels.

Specs:
OSX 10.9.5
Processor: 3.2 GHZ Intel Core i5
Memory: 8GB 1600 MHz DDR3
Graphics: NVIDEA GeForce GT 755M 1024MB

Thanks,
Acid

I doubt you're going to like the performance that a 755M with only 1GB of VRAM is going to give when trying to run five accounts (you don't actually mention how many you're trying to run).
