Currently have a 2011 MBP which does an outstanding job with any game I want to play via Windows/Bootcamp. I've all ready replaced the hard drive and I realize I might be on borrowed time as this hardware is 4+ years old. I realize that I'd probably get just as good performance if not better from an iMac, but I do travel on occasion and it's nice to bring gaming with me, other than my iPad. My impression is that for more demanding gaming, I need dedicated graphics such as the top tier $2500 MacBookPro with AMD Radeon R9 M370X with 2GB GDDR5 memory or the $1500 iMac with NVIDIA GeForce GT 750M with 1GB video card. Thoughts? Are there lesser Macs that will do the job for AAA gaming? My impression is no. Thanks!
