I very much love my FX-8320 / R9 270 / 8GB DDR3 2133MHz system. The CPU was a hell of a steal when I bought it in 2013 for $135 CND, when the cheapest i5 was $185 CND. Now, sadly, there isn't a single i5 for less than $230 CND and even the FX 8xxx series is over $200 CND...
Anyhow, I chose the AMD FX processor as an upgrade to my Core2 Quad Q8200, because it soundly trounced that CPU in every possible scenario. People tend to ignore how AMD includes every CPU feature, such as hardware virtualization, in all their CPUs, with all their processors, where Intel does not. The FX is a well rounded, competent CPU for all workloads. Is it the best? Nope. Is it the worst? Nope.
Some of the things I do with my FX 8320:
Linux:
- Blender Game Engine, 3D modeling and C++/Python based game logic.
- Audacity audio editing.
- Sunvox multi channel synth and music tracking program (amazing program btw).
- C++ programming and compiling with 8 cores using GCC (more than twice as fast to compile the game I was building back in 2013!)
- GIMP graphics editing, textures, etc.
- Virtualbox running 2 or 3 SWGEmu servers (Debian 6 and 7) at times in a Windows 7 host. Not all the time, just when programming, but the experience was always smooth and uneventful.
Windows:
- Games such as Guild Wars 2, Planetside 2, Star Wars the Old Republic, and many others run quite nicely at 60 FPS with 4x MSAA or FXAA, with shadows on low or medium. Generally speaking, I am kind of snobby when it comes to graphics (if only EQ2 didn't look and play so awful...), but what I appreciate most is a smooth frame rate as much as possible. My setup, on my 20" 1600x900 monitor, delivers this for me and it did so on a tight budget. Sure, the frame rate drops when too many people are around in PS2 or GW2, but the same thing happens to overclocked i7s so... yeah.
I don't regret my purchase at all. Not because I am a "fanboi", but because the reality is that the system "just works". Given how I don't really play games all that often anymore, I probably won't upgrade for 3 or 4 more years at least, provided the system doesn't blow up, etc. lol...
