Super important power supply question
-
What I want is the best performing system, so basically it comes down to
- If the power supply won't be a factor, keep the 980TI
- If it will be a factor that lowers the performance because there's not enough power for the parts, then I keep the 980 one.

If the biggest difference is the graphics card, and that is what you want, then it's a pretty simple thing.
Return the one with the lower card, and up the PSU in the other.
These are HP Envy machines which are super small, and I don't think the form factor of the PSU is mainstream or that I could just swap another one out, if I'm wrong please tell me which one to get and that COMPLETELY SOLVES MY PROBLEM THANK YOU!!

@creayt Dimensions are roughly 5.6 x 6.5 x 3.5 inches.

Nice! I'm going to call them and be like "this is the highest caliber Envy you sell, how did you not put one of these in it?"

The power supply will only matter when you are running GPU intensive things.
That said, since you are overclocking it, 500 might not be enough for the small video card because you'll be pulling extra power that wasn't accounted for in the original specs.
But without testing you won't really know.
Also, You don't don't to be playing games to hit the GPU... things like Bit coin generators can use the GPU for better performance.

@Dashrender What did you mean by the small video card? It looks pretty huge to me.

the one with lower specs (was that the 980?)

@Dashrender Ah, ok ( yep, the 980 and then the other is the 980 TI ), so you're saying that with overclocking even the lesser-powerful system risks not having enough power. Gotcha, thx.

Exactly. Who knows.. it might have enough power, but until you try, you just don't know.
Also, being underpowered manifests itself in all kinds of strange ways. BSOD, video freakouts, apps crashing, slowness, etc. At least you're thinking about power now, so if you start seeing these behaviors you have an idea of what the problem might be.

To anyone who's curious, in practice my impression is that it makes a HUGE difference. Processor performance on the 980 box is much MUCH better than on the power-strained TI box, which I'm sending back. When overclocked to the same speed, the TI box with identical settings hovers down below 2 Ghz most of the time while the 980 box is up above 4 most of the time w/ load. The disk performance ( same exact drive, just moved ) w/ rapid mode, which is very proc dependent is also much better on the 980 box, breaking 5 GB/s read/write. So, yeah, question answered. The 980 box is also quieter, which I adore. Good thing I don't play many games and the card difference isn't a huge deal, or at least I keep telling myself that.
