Ehh, if I could get better temps (maybe wring out another 0.5ghz on my CPU), and make everything very quiet it might be worth it... Lots of pros and cons to weigh here though. Custom loop is still down as a maybe for me.
Now that I have 2-4k instead of 1-2k textures, the game falls below 60fps sometimes when I'm up and about outside. Should be a CPU bottleneck. There isn't a CPU that's faster for this game which exists, so I've started to hit the limit here.
Yeah, CPU bottleneck for higher res-textures. How about that.
If you go back and do a stress test you know you were able to complete successfully but now fail, you have degraded. I don't think performance changes.
For example, back on my 4670k I used to be able to do almost 8 hours of the old x264 test @ 4.6ghz 2.15v/1.42v. A year later I found out the chip could not last over 5 minutes at the same settings.
