Is it worth it for me to overclock...?

I can vouch to a case making a difference. With the way I have my case fans, air is sucked in on top over the CPU cooler and my temps stay pretty damn cool. I have to wonder if it would be even more cooler with the heat sink using a push/pull config.

Looking at your case you do have fans on top. So that's probably why. Tell you the truth, that may be a bear to install the 12v 8 pin MOBO connector if it's like mine on top there with those fans.

Here's where mine is located.

Having intake fans on top is completely counter intuitive since heat rises and you want the fans on top as exhaust. Your images aren't working either.

I don't have intake fans on top. Never said that. He does. I said air is suck in on top. I have negative pressure in the case and air is drown in on top that pours over the CPU heat sink.

Images work for me. They are hosted from imgur.

I do? The fans on the top of my case are exhaust fans. I installed them. All three 140mm Phanteks fans in that photo are exhaust. The only intake is the 200mm in the front of my case.

It is still strange to draw air in at the top of your case. Ideally you want airflow to be drawn in at the bottom/front and flow towards the back/top. Simply because hot air rises and typically CPU coolers blow towards the back. But if it works for you, whatever.

BTW, I just did a stress test run on my CPU in Prime95. I have a stable OC at 4.0 GHz and 1.2V fixed. I tried the run at 1.18V but I got blue screen even though my computer was running fine for 24 hours like that. I'm going to see if I can get 1.19V at 4.0. Max temp was 82C during the run.

Let me try again. And don't knock my setup.

All of my case fans draw air out of the case. At the top is a grid with holes and air is sucked from the top. I do not have fans at the top. The air comes down from all the fans and rushes over the CPU heat sink. I wanted hot air to be drawn out of the case. So what I have is negative pressure. I have read you want to have fans blow air in the case, but I'm not doing that. To me, it makes more sense to blow the hot air out. The only cool at that gets added to the inside is drawn from the top and I can feel it. I have a total of four fans. One at the back, one at the front and two on the side. I control the two on the side with a fan controller. If I don't they are very loud. They are red LED Cooler Master fans and I think they are rated at at least 2000 RPMs. Can't remmeber the CFM. But they work great. I have the fans set at 1300 RPM.

Move the two side fans to the top blowing out and turn the front around to make it an intake fan. I guarantee your temps drop across the board.

Your CPU, GPU and RAM would run cooler if you re arrange those fans. Cooling the components is not just about removing as high a volume as possible from your case. Its about getting airflow MOVEMENT across those components/heatsinks. When you have a fan in the back and in the front blowing in opposite directions, they are fighting each other. You will end up with areas of stagnation in the middle.

Hmm. I guess that does make sense. But my thinking is that they are not fighting each other sense the fans are drawing air from the top at the same time.

And the air from the CPU heat sink blows towards the back fan to suck out.

Think about the airflow patterns that are setup in your case right now. Yes, they are both drawing air from the top, your back fan is drawing air from the top back and your front fan is drawing air from the top front. In the middle you have stagnant areas where there isn't much movement. The fact that you have two side fans blowing out as well minimizes this but still, its not ideal.

Hey, I want your guys opinion on what you would chose for a monitor upgrade and why: Its between a 27" 1440p 144 Hz 16:9 IPS or an ultrawide 34" 1440p 75-100 Hz VA panel monitor. Which one? And which one do you think would require more GPU power to drive at its full potential?

I would get the 27". They both would probably be about equal strain on a GPU.

If you plan on playing games at max settings, your R9 390 will struggle on the 34" ultrawide. Especially if you want to reach the 75-100hz range.

Yes I'm aware of that. It already struggles to drive my 60Hz 1440p Dell. I'm planning a GPU upgrade as well, not right away, but probably in a year or so. I'm not sure what card I'm going to get yet, but I think I'm going to switch back to Nvidia, which is why I think I also want a G-sync monitor.

Ah I see. If you're really interested in ultrawide, LG is making a G-Sync one in 1440p that's IPS. Not sure if it's out yet, but if you play games that benefit from the extra width, ultrawide is pretty epic.

yea I am definitely leaning towards ultrawide, they do look pretty epic, and not just for gaming. I also record a lot, its my primary use for my PC. I have a small Samsung TV (24" 1080p) that is normally in our guest bedroom but I will occasionally use it as a second monitor and its a HUGE help for recording.

The reason for my question is I am having a hard time determining from online reviews whether it would be a bigger upgrade going from 60 Hz to 144 Hz or from 16:9 to ultrawide.

Depends on what you play. If you primarily play FPS games, 144hz will be noticeable. If you record a lot, ultrawide maybe very beneficial to you. Keep in mind, g-sync + high Hz rate + ultrawide = $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$.
