OP, you left out a crucial detail:
What resolution will you playing SWTOR?
Your rig is perfectly suitable for lower resolutions (1366x768, 1400x900, 1680x1050) and probably fine for 1920x1080, but you never mentioned what monitor you are using.
It is not an idle point as the resolution determines the number of pixels on the screen. More plxels needs more CPU and more GPU/VRAM.
Case in point, my own computer has issues playing at the highest settings with an i7-4770K @4.2GHz, 16GB RAM, SSD, and RX-480 8GB video card (overclocked to 1342Mhz). On paper my system is very powerful by SWTOR standards and quite a bit faster than yours.
The reason why it has trouble? I play SWTOR on 3x 30" 2560x1600 monitors. That's the equivalent of six 1920x1080 monitors.
This is why the resolution question is non-trivial to this conversation.
Like nearly everyone else I recommend the following changes:
- go to 16GB RAM (2x8) for more capacity and dual-channel
- go SSD, the access time difference is stupid
- perhaps a faster CPU, SWTOR doesn't need a lot of cores so it relies on IPC. You don't necessarily need 4+ cores, but you do need a high clockspeed. NB: do not compare the AMD clockspeeds with Intel, the current AMD chips are much slower clock-for-clock (the upcoming Ryzen will be better but still not as fast as Intel per clock, but could be a *LOT* cheaper - if you go that route you'll have to replace the motherboard too)
- this is a personal preference, go with a Cooler Master Hyper 212 EVO CPU cooler it is one of the best price/performance coolers out there (and not much more expensive than the Freezer 7). I have used the Arctic Freezer 7 myself, it is no match especially as unlike the Arctic the Hyper 212 EVO can have 2 fans in push-pull for better cooling. If you don't overclock you won't care, but if you end up with a different CPU (especially a K series) and start overclocking you'll thank me later
Once you tell us the resolution you play SWTOR we can make further suggestions:
- *MAYBE* go with a higher video card, the 1060 is a good compromise although given you kept your last computer 9 years I might suggest a 1070/1080.
- depending on what video card you end up with you might want a slightly larger power supply, 600W+. I personally never get lower than 750W and I current use a kilowatt PSU, but I do more than game on my computer (apart from the 3x 30" monitors for gaming I have 4x 22" 1080p screens above them so I can work and play at the same time)
