Thinking of getting the mid model mac mini 2014 with the 8GB of Ram. Will it be powerful enough for a single win 7 VMware image running? Will use occasionally for some of my old windows apps. I will also use the mini for streaming movies and other standard stuff like email, Internet, garage band recordings and picture editing. I know the i7 quad core is better for vm but I am concerned about the outdated graphics chip years down the road. If the single core i5 will do a single VMware image running I think I will get the 2014 model.
