Update since he is to busy playing TF2 now:
He didn't plug in the 24 pin mobo power connector properly.

So let me get this straight: You're going to spend 1200$ on a Titan X but want to lower RAM cost?

I need at least some sort of goal, because randomly throwing together the most expensive that fit isn't a good idea.

This should be a type 3 build: There's a set minimum performance goal, but money is a secondary concern so if upgrades make sense they get put in.
So if I knew what you're trying to do with this build it would help a lot.

Also when are you going to build, because Kaby Lake / Zen and possibly Vega will be released in early 2017.

Two builds.
I mostly ignored osu because well, that shouldn't be a problem.

Option A, more fps on low settings, but less when you're really cranking the quality up:

If you can spare another 25$ you could an i5-6600 but the difference would be <8%, even in best case scenarios.

Option B, not as good for "looks like quake" low settings, better at higher quality and higher resolutions/DSR/render scaling >100% in overwatch:

Actually 1200 USD or still 1000 USD + shipping?

Have we talked about FreeSync?

That case won't improve by adding more than it's worth in fans. Either get a cheap case that comes with multiple fans or get a better, more expensive one. You can't replace quality with fans.

The Rosewill Photon is a bit weird and I wouldn't take the risk with other options available at similar prices.

Not going over the other peripherals for now.

It's an Acer, not Asus.
It does not have G-Sync.
What is going on today?

#8
It's a Maxwell Titan X.

Does everything work now?

Did you edit right after you posted?
I swear the post ended right after "270x".

And it does indeed need to be in the lower one, otherwise you're not using your GPU.

No idea then, the program should be installed as well. Maybe search for Crimson, no idea what it's listed as in windows programs.

Picture? Still guessing whether or not you've actually plugged it into the GPU now.

Better cooler, better PSU. Didn't know your budget so I tried to keep the price about the same.
Should probably also get a better case.

Yeah, but which driver did you download?

Could I get a picture? Because usually the AMD GPU would be the lower one and you used an AMD program for settings before, but since it just now started asking for that driver I'd rather make sure it's not one of those weird "Hey let's flip everything upside down" PCs.

GPU-Z might also be useful to figure out which GPU you're using anyway, if you don't know. CPU would be interesting to know too. CPU-Z, when in doubt.

Try searching for "Catalyst".

How did you install the driver?

Also since you "found another random HDMI port" I'm guessing that one is up high on the motherboard from the integrated GPU and only one is actually from the discrete GPU down on the bottom. Which one are you using right now and which one were you using before?

Well are you still losing input?

I think you mean AMD Catalyst. It's probably there. Have you tried the search function?

Access what?
Does it work now?

DDU does not depend on you finding the AMD icon. Uninstall properly with DDU, then try again.

Also Windows 10 likes to randomly "update" your drivers with a freshly microsoft approved version which is a year old and doesn't support the GPU you're using. I'm not kidding.
