Questions about R9 390 reliability/heat profile.

I'm looking to build a PC this winter and out of all the mid-high end graphics cards the R9 390 looked like it has the best performance to cost ratio and includes a very impressive 8 gigs of VRAM which I'm sure will last me well into the future. The only problem is that my current PC runs both a AMD GPU (HD 7950) and CPU (FX-8120) and I have had very bad experiences with it crashing. I'm almost certain it's an overheating issue as the problems seems to mainly persist during the Summer when the CPU gets over its max temp and the GPU runs high 70's. With this information would you recommend a R9 390 with ambient room temperatures around 81 degrees Fahrenheit. I've bought a portable air conditioner, but I'm still worried about issues that might arise during heat waves.
Also on a side note does the R9 390 continue to rise to extreme temperatures when operating at 100%. My HD 7950 has gotten over 90c during benchmarking tests (although not while playing games).

You should get a case with good airflow and an aftermarket cooler for your cpu to keep the temparatures down. The fx 8120 will also bottlneck the 390 in some games

R9 390 is a good GPU, but it produces more heat than HD 7950, so if you have issues with this setup, you have to fix them first.

As mentioned above, you need a good PC case with good airflow and an aftermarket cooler for your CPU. When get the CPU cooler you may try to overclock it, to reduce some bottleneck.

What is your PSU? It is very important for power hungry GPUs like R9 390.

81 F is actually not that hot for an room temp at all, my old apartment use to get close to 100F and at stock settings your computer should handle it no problem as long as you have proper airflow. Are you by chance using the crappy stock AMD cooler? Your VRM's on your motherboard could be getting to hot..

I got my current PC prebuilt and it uses a Corsair liquid cooling system (not sure which one). I'm going to build my next PC and I'm aiming for an intel CPU as I read their TDP tend to be lower. Also, I was going to ask this in a separate thread but how long does a mid-high end CPU like the i5 6600k stay relevant before becoming a bottleneck for newer, high grade GPUs.
On another side note my current PC case is quite small, if I'm investing around $650 for the combined processor and graphics card what size case is recommended?

For best cooling preformance withouth going overboard on the size a mid tower case would be best.I ussually recomend Phanteks enthoo pro m , fractal define s or nzxt s340, they are all cases with great airflow that arent too expensive.
I5s ussually stay good for a long time, something like the i5 2500k that came out in Q1 2011 still dosent bottlneck, but there is no way to know for sure how thing will change in the future, my guess is that the i5 660k is gonna stay good for gaming for a long time.
