R9 390 Bottleneck

[SirDarknight]

I recently got a Sapphire R9 390 Tri-X.Haven't hooked it up yet, waiting for the PSU. And you'll get a heart-attack when you hear what CPU I have. It's an i3-2120 I know it's gonna bottleneck as hell. But what I wanna know is how much.

I mean, how many FPS am I gonna lose over this CPU?

 

My current config :

 

Quote

i3-2120 3.30 GHz

Gigabyte H61M

8 GB DDR3 - 1600 MHz

Sapphire Nitro R9 390 Tri-X

1 TB HDD

Corsair VS650

 

Don't worry, I'm gonna get an i7-3770 soon.

Try it yourself?

i3-2130 even bottleneck my old 7950 in a few games mostly open world like GTA.

Before you upgrade your CPU, your Power Supply and Storage Drive could do with an upgrade.........

[smokefest]

Hum... Upgrade CPU first ???

Power supply is 650 wattm good enough.

Storage is HDD 1 TB , its not a SSD but not everyone wants to put his $$$ budget into loading time...

The quality of the unit is quite shitty. The amount of wattage is perfect fine.

There is no excuse why an i7 rig doesn't/can't have an SSD............

[smokefest]

I wouldn't change a PSU if the wattage is good. Who cares about quality the guy didnt ask for how to get top quality PSU..... It would be a waste of $ to change that PSU if its working correctly.

Also having an i7 dosnt change anything at all concerning the need of a SSD.

I agree that SSD is op and a must, but it just not necessary in games.. it only help for the loading time. It is great in windows and applicatinos tho and personnaly, I would buy an SSD to at least 120 GB for the operating system

There's more to PSUs than just the wattage....

I've never seen a desktop PC with an i7 have a HDD as it's primary drive............. NEVER...........

If he can afford an i7 then he may as well have an SSD

you obviously have no idea of the power draw figures for an R9 390 GPU...you do require a top notch unit to run these safely.

[smokefest]

No need to change a PSU if it does the work. He already paid for it cant you understand that.. The point of the post isnt to point out every thing that cud be better... ALL HIS entire pc cud be better we all knoow that. You simply dont change sumthin that aint broke. End of story.

Not having a SSD is not the best but it dosnt change anything in games. 

the guy asked for games purpose.

[smokefest]

650 Watt is fine for r9 390.

Go buy a 1000 watt like all the people who spend money for useless things...

I really tried hard to be nice but you didn't get the hint.

 

You're being ignorant.

 

R9 390's require a GOOD Power Supply. his power supply is below Mediocre and is only better than those terrible OEM ones included in Prebuilts.

Just now, smokefest said:

He already paid for it cant you understand that..

He can get a refund or return or resell it.

 

if he can propose to buy an i7 then surely he can buy a DECENT power supply.

Oh ffs....

 

This isn't even "Could be better"..... This is how to salvage a badly designed parts list.

You have no idea what you're talking about and frankly your behavior is that of a troll.

Yes, but I am a responsible human being. As a technologically literate person, I inform people of issues with what they are doing if there is a deep underlying issue that should be fixed.

And? GTA V stutters like hell if you use a HDD.

you don't understand...there are shitty quality 750W PSU that will bust under heavy load...and there are top notch quality 550W (like the one i'm using in my own build) that can safely power an overclocked core i7 and an overclocked GTX 980ti without breaking a sweat...wattage doesnt mean anything and the corsair VS is a basement bargain chineese unit...it would not use it to power an R9 390 GPU, end of the story.

Also, yes he could upgrade is machine and be a death defying redneck by keep using the old PSU...but if the PSU fail it can and will most likely take down many other components with it...including is brand new graphics card...do you understand better now?!

[smokefest]

I have no strutter in GTA all my games are onmy HDD. 0 struttle.

Maybe you need help to configure your pc or build it ?

[xAcid9]

So OP is waiting for his VS650 PSU or upgrading to a new one?

No one here is recommending a 1000w PSU, and we all agreed that the watts on that PSU isn't the problem, what we are recommending is a better PSU than a Corsair VS series since they aren't the best out there and the R9 390 does require "clean" power. I personally would recommend a Seasonic S12II 620w ... but that's just me!

Your i3 is definately bottlenecking the 390, not sure by how much but here is a digitalfoundry video comparing the i3-4130 vs i3-6100

 

if you compare the 6100 and the 3770, they get roughly the same single-core performance but the 3770 has more than double the perf. on multi-core (I know userbenchmark isn't the most precise but it's a good guide for rough estimations).

 

So adding those two I'm sure you'll see a big difference when changing to a 3770!

[SirDarknight]

OK. Guys, calm down!!! No reason to get so excited over something so petty!

 

First of all, I've already paid for the PSU & refund isn't possible (I chose it cuz it's the only 650W PSU within my budget), although it's not the best PSU in the world, it does it's job. I think I'll be fine if I don't try OCing. And will upgrade it when I have the money.

 

Secondly, my first priority is the CPU cuz it's definitely gonna bottleneck my GPU & I won't be able to get the bang for my buck.

Thirdly, loading time doesn't matter that much but SSD is in my list.

 

Thank you got your replies.!

Didn't know my PSU is tier 5, Still alive after almost 4 years of constant gaming.

Use downsampling and cap your frame rate for "smoother" gaming when CPU bottleneck happen.

Me has...I own one as the PC I use in Beijing...i7 3770 and other shizzle (quadro GPU however...great gaming performance you know...) as it was a machine my father's business used for rendering models and whatever so...only a 1TB hard drive

Yeah I understand but it's just...sometimes a bad PSU will blow up if it's stressed (within ratings) for too long  (or if the temps inside the case get's over something like 40C)

 

http://pcpartpicker.com/product/nB3RsY/seasonic-power-supply-s12ii620bronze 

This is a much better and it's also decently cheap and yes I know you already have a PSU but wattage and efficiency=/=quality. I know plenty of people who's used shitty PSUs with high power consuming parts (me included) but after witnessing 3 PSUs blowing up (although they were sufficiently rated to handle load) I just like suggesting people to stay on the safe side

But, that particular PSU doesn't have 2 8-pin PCI-E connectors (which I'll need for my 390)

Oh dear god.

Austin had his house burn down because of a shitty PSU. Does OP want his house to burn down? No.

[SirDarknight]

How about EVGA 600B ?

But seasonic's own website says otherwise (go to the cables tab) and reviews of this PSU...This isn't some cheapo no name chinese PSU you know...which has only like a single 6 pin on a 850watt  

[ivan134]

An OC'ed 480x is a bit faster than a 390x, but this is about what you should expect from your 390 with that i3. It would actually be even worse than this because he's just emulating an i3 using an i7 with a larger cache

As for the PSU, quality is more important than quantity. I'm using my 390 on a 550W but top quality PSU. Yours is a risk.

 

[Guest]

Get a seasonic made psu. They are THE BEST psu OEM ever. Plus, most of them are pretty cheap too. ?

 

[SirDarknight]

Most probably the information on PCPartPicker is wrong.

 

 

 

As the information stated on Seasonic's website says otherwise, I'm gonna mark it as incorrect.
