Graphics Card Upgrade From GeForce GTX 780 to GTX 1080?

Hello

I've been considering upgrading my graphics card from a GeForce GTX 780 to GTX 1080, but I'm concerned that I wouldn't see much benefit.

I'm using an ageing Asus Rampage III Extreme motherboard with a Intel i7 980X.

This motherboard obviously has an older PCIE slot so I assume I wouldn't get the same throughput as a newer motherboard resulting in a bottleneck?

Is the upgrade worth it? Would I see any improvements?

Thank you
 
The speed increase of the PCIe bus between 2.0 and 3.0 is irrelevant with one card. I think you'll see a significant improvement in gameplay, but I'll let others comment on CPU bottlenecking.
 
Is the 980X overclocked? - at stock you'd likely not be fully utilising a 1080 but with a reasonable overclock on the CPU wouldn't be too badly mismatched.

That sounds promising, thanks.

Not at the moment as I had to go back to the stock heatsink and fan. Once I get my new AIO cooler it will be OC'd again.

Thank you.
 
As long as you get your CPU clocked up to ~4 GHz, you shouldn't be bottlenecking the card in most situations.

A GTX 1080 is likely the end of the road for your setup though. When you come to upgrade it again in a couple of years, you'll want to get a faster CPU and PCI express 3/4 (if 4 is around by then).
 
I would go for 1070 with your setup to be honest.
And next year upgrade the whole rig with kaby lake 7700k etc. Buying 1080 now is a mistake, there is 1080ti coming soon which could bring prices on 1080 down so hold on just a little bid longer or buy 1070. You didnt say what res you playing at but 780 is not a slow card.

I don't think a GTX 1080Ti will affect the GTX 1080 pricing at all. The GTX 1080Ti will just be launched at an even higher price point.:cool:

It kinda is now with modern rendering techniques and mature drivers.

It hovers around RX 470 level, or below GTX 970 and 1060 3GB.

It's not super slow, but not amazing either.

780 performance took a nose dive in NV gameworks games right after the 9 series was released. A lot of people suspect it happened on purpose. It started off on par with a 970, but is now noticeably slower :/

I know, I had one.

People look at this PCI-E 1.0 2.0 or 3.0 thing the wrong way round.

It is not PCI-E that will limit your performance, it is the monitor.

It is easy to get 60 or 120 fps on any version of PCI-E but it is much harder to maintain very high quality settings as the resolution increases due to the monitor.

I dont know about the CPU bottleneck business but i do have 50pence about 780 to 1080.

In my experience my 1080 FTW(before i returned it) is around equal to or +/-15% to my SLI EVGA 780 SC.

So imo is a massive jump, especially in my case where i could get away from SLI problems and also a big savings on energy consumption oh and heat severely reduced :)

Instead of a 1080 get a 1070 and add a little extra to whats left over so you can get a newer cpu, motherboard etc.

Maxwell has certain optimisations to the shader hardware that when properly optimised for a game in drivers with all other things equal gives it a fair performance increase over Kepler cards on that alone and due to the nature of it you can't easily make the difference up just by overclocking Kepler cards.

People underestimate 780 performance - with an overclock on it my GHZ edition was mostly running pretty close to a RX480 (aside from 1-2 titles). For some reason a lot of benchmark sites are running results off them with a limited 900MHz (reference) core clock when most (they didn't really sell reference clock 780s) will actually be boosting to atleast 1006MHz sustained and often a fair bit higher i.e. my B1 GHZ out the box boost was like 1189MHz.
 
I went from a EVGA GTX780 FTW which is not far off 780ti performance to my current 1070 and in some games I have seen double the performance so it is a well worthwhile upgrade. The downside is that the game I play most, TS2017 which mostly uses a single cpu core I am massively cpu bottlenecked now and the gpu load is usually at 66% or less.

Yup - went from my 780 GHz which was boosting to 780ti performance out the box more or less and ran mostly clocked another 10% beyond that to a bog standard Palit Dual Fan 1070 (1911MHz boost) and most stuff is around +70% to double the performance give or take and only a mild overclock on my 4820K.
 
I would like to thank everybody for their comments and advice.

I've decided to upgrade to a GTX 1080. I thought I would go for the Asus unit below. I would have ordered an EVGA card, which is the same make as my current card, but I understand there's a little problem with the EVGA cards at the moment.

I thought I'd also invest in the Corsair H100i AIO cooler so I can overclock the CPU again.

Finally, I thought "what the hell, in for a penny, in for £1500.00", and threw in the 2TB Samsung SSD".

This will probably be the final upgrade for my current PC. I'm hoping, finances allowing, to build a new one next year and, perhaps, give this PC to my son. Unless I can think of a better use for it.

Now I've got to decide what to do with my GTX 780 and also an even older GTX 480 ;)
