Nvidia GTX 580 to 770 - will I notice a difference?

Recommended Posts

Quite a simple question (hopefully). Currently have a 580 but thinking of upgrading to a 770 - 780 is a bit too expensive for me at the moment. Performance on the 580 is pretty good, is the 770 a better card? It may be a newer card but I'll be going from an x80 series to an x70 series which in theory is a backward step.

 

Any thoughts? It's for P3D2 purely, nothing else.

Well, as someone who made the jump from a 580 to a 7704Gb, I can say quite categorically that yes, there is a noticeable difference. However, although I have experienced an overall improvement in frames of about 8%, in clouds, I have noticed about a 25-30% increase in performance. This is particularly noticeable around airports with 8/8 cloud cover. With the 580 I used to notice the frames drop significantly in these conditions, but now with the 770, there seems to be very little hit.

I am a noob when it comes to video cards.  I currently have a GTX 460 1gb.  

 

My question for Rockliffe is, in light of Luis_KMIA's reference to jetlinesystems chart, is the GTX 770 4gb video card you are using a dual-gpu card?  Are GTX 770 4gb cards even available as dual-gpu config?  I just don't want to make a $400 mistake.

Hmm, well, you are asking a question that I'm unsure about. I don't know what a dual GPU is! If you mean is it some kind of SLI setup, or has effectively two GPU's in the same chassis (?!) then no. Perhaps someone else can drop in and clarify...

P3d is much more sensitive to GPU power than FSX is. A 770 is roughly equivalent in performance to a GTX 680 so you will see an improvement in performance that is noticeable.

In the Jetline system guide that Luis_KMIA shared, it states, "The Nvidia GeForce GTX 690 and other dual GPU graphics cards to be a significant performance decrease to FSX." 

 

How do you know which Nvidia cards are dual GPU and which are not?  I'm assuming the GTX 770 4gb is not, but that's a $400 assumption I don't want to make.  I want to make certain it is a single GPU card.

The dual GPU cards will  have a 9 in the name GTX590 , 690, 790.

FSX does not like Dual CPU cards or SLI in general, P3Dv2 will be getting SLI support so there may be a future for these dual GPU cards.

But if it is for FSX then a single card will be better.

I did three things yesterday:

 

Replaced GTX 650Ti with a GTX 770 card (at least double the graphic power")

Installed the "wonder driver" 355.70

Installed v 2.2

 

I see no improvement in some challenging places such as KSEA and KBFI over Orbx PNW. It still turned into a slide show occasionally. In less challenging areas, P3d is extremely smooth before and after the upgrade so I couldn't tell the improvement. Of course your mileage may vary with a new video card, I think I will return the $300+ GTX 770 and replace it with an i7 4770K at about the same price. I believe my lowly i5 4440 @3,3 Ghz is the performance bottleneck.  Anyway this is just my personal experience for your reference.

Did you remember to delete your shaders ?

I would wait till refresh comes out before upgrading your CPU they will be the same price  be 100mhz faster(base clock) and use a new TIM that will drop CPU temps by 20C which may allow overclocked Haswell's into the 5ghz club without liquid nitrogen cooling.

I did a full 2.2 installation after replacing the card so the shaders is not an issue here. My point is when you have some doubts about your HW spec for P3d, fast CPU probably gives you more bang for your buck than a new graphic card.

I agree on that one - I think my 3770K helps a fair bit, along with not using payware aircraft.

 

Thanks for all your contributions people! Think I will go for a 770 :)

Well slightly bizarrely a broken coffee machine has given me a bit of extra budget so it looks like I'll get a 780 after all :)

I went from a 570 to a 770 (4gb) and have been pleasantly surprised. You wont regret your purchase.

According to the experts. You would be better off with two 580's in SLI for p3D..

How so? I thought SLI wasn't even available yet on P3D? I only have a single monitor setup anyway.

The problem with that is the GTX650Ti will then become the bottleneck and you will be back to square one.

A 4770 needs a GTX770 or better.

I definitely agree with gboz

It’s a balance act, isn’t it? If you fly a lot over metro area doing touch and go, especially over KSEA and KBFI with Orbx PNW installed, CPU can become the choking point of frame rate. At that point the graphic card becomes irrelevant. In other situation such as IFR condition in heavy cloud with shadows and HDR on then graphic card will choke and FPS suffers. You just have to know your type of sim flying and choose the right hardware to maximize the bang for your buck. Since I am happy with P3d 2.2 for most of the time, I will hold off the CPU upgrade for now. It is very frustrating to find out my system built just 4 months ago will become obsolete by 3Q this year because the new Haswell refresh K chip is not supported on my Z87 board. IMHO, it is better to start saving money for the next system in a couple of years to enjoy a huge performance jump than throwing money to the old one getting only small incremental improvement.

Hello! Sorry to here, but I will not be a new thread assumed. I currently have a Asus GTX 660ti 2Gb OC. It makes sense to change the new card ?
Thank you.

Hmm maybe this is why i have relativ poor performance with my GTX780ACX SC@1110MHZ. Whent back to FSX/DX10 in KSEA/CYVR in the Lancair with more than double the performance (50-70fps)

 

Yesterday i was down to 10-12 fps around CYVR in P3DV2 for no reason i can remember. Settings the same as the other day with 35-50fps so will try the "wonder driver"
