Thank you Mr. Drillingmachine, first time here didn't see the male part! I also purchased few other games I was unable to play on my laptop such as "Thief" or "The Forest", I'm not certain how heavy of games they are but I just wanted to name a few that I couldn't play on my laptop.
But if I can run Overwatch and games with similar requirements at highest performance while having no issues with alt-tabbing for smaller multitasking, that would be perfect. To hear that it will be much cheaper than $1500 is a great news though! Do you have any recommendations by chance?
I agree what Mike_Soda said. If you can build your own machine (or pay to someone that builds it), it's best choice.
As your demands are not huge right now, you basically have three good choices if you ask me:
1. Buy cheap machine and upgrade heavily (means changing motherboard) later.
2. Buy cheap machine that has great upgrade path (without changing motherboard)
3. Buy high end machine that will last very long performance wise (without changing motherboard).
For 1, you are saving lot of money now but if your demands change, you need to upgrade quite heavily.
For 2, only wise option is Socket AM4 that is not yet available. About a month or so?
For 3, you can upgrade video card if you want games run better, CPU should last at least 5 years even on heavy use.
Make a pick.
