So, If you have any suggestions for PC's or steps to take to protect a PC from all the crap online or just getting slow I would greatly appreciate it!
The virus/malware "issue" on Windows is overblown by non-Windows users. Sure, it is the most dangerous system for viruses and malware, but you can install a couple of relatively non-intrusive programs to easily combat that. In my opinion, it really isn't worth it to spend $1500 on a gaming computer, especially a Mac since games on Macs are very limited. For the same price, you could build a custom computer that would rip through any software you threw at it. But in the end, if you want to stick with Apple then you're limited to the choices they offer, which means chances are that Pro 15' is the only one that will be able to support high-quality graphics and such.
If you want a laptop (not a desktop) then I'd just get a solid $600 laptop with optional NVidia or Radeon graphics. For surfing the web and other things that risk virus or malware attacks, you could always install a copy of Linux alongside - Mint is fairly intuitive for beginners, and Ubuntu isn't bad if you aren't afraid to get dirty with the command line. In actuality, you can have a machine that is as safe and powerful as a Mac for half the cost if you install a good SSD - however, you won't quite be able to match the battery life of a Macbook Pro with a budget laptop.
The short answer is that if you want to stick with Apple, you buy what Apple offers, or you swing for a PC.
