My 780Ti giving all the signs of having given up the ghost, I look into buying a new card with specifically P3D in mind (lots of OrbX sceneries, A2A/RealAIr/Milviz kind  of aircraft). I run a 4770 at 4.4 Ghz, presently with a 2560*1440 27" monitor.

 

I try to make up my mind on two issues : 

 

- should I wait January for the 1080Ti  or would a 1080 be enough ? I mean, would  a Ti bottleneck the CPU anyway and be an overkill ? 

 

- Also, would a Ti be better if I go for 3840*2160 ?

 

Again, this is to run P3D. Any ideas ?

3840*2160 requires RAM so the more the better

I am planning on 6G min as I use that UHD res too

 

My old videocard of only 4G may be failing as after 30 minutes my UHD goes black. Hope its not a UHD issue

 

I also have a 1920x1200 running alongside

 

 

should I wait January for the 1080Ti or would a 1080 be enough ?

 

Perhaps this link will help - http://gpuboss.com/gpus/GeForce-GTX-1080-Ti-vs-GeForce-GTX-1080

GTX1070 it is already too

3840*2160 requires RAM so the more the better

 

thanks, a good point ! You think that 8 meg is short for 4k, 12 better ?

yes, it does and no, it does not  :smile: . It clearly shows the (presumed) differences but do these differences matter in P3D, specially coupling the card with a 4770 ?  

If your budget extends into the GTX1080 range, I would definitely wait for another couple weeks for the 1080Ti. In the long run you will not regret it. It seems significantly more powerful than the 1080 as per the link that Jim posted.

 

That said, you are unlikely to notice much, of any difference in P3D between the two right now but maybe down the line. More modern games will also benefit from the Ti.

 

Right now, even the 1060 6GB versions do a good, balanced job with P3D when the rest of the system is up to spec (fast CPU, motherboard and ram). Skimping on any of these will only reduce / limit any benefits that the 1080Ti will offer in P3D. Go with 16GB ram and aim for good branded ones that can run high MHz in XMP profile. 2x8GB sticks is better than 4 x 4GB on dual channel boards. The price of DDR3 is coming down now that DDR4 is mainstream. Don't run 12GB ram, not a good configuration on a 4770 CPU (dual channel) system.

i was refering to the 12 GB of VRAM of the Ti (or 10 from some sources), I've 2x8 GB RAM with the 4770.

The real difference in terms of performance will come from the new Intel kaby lake processor with stock clocks at 4.5Mhz probably capable of overclocks at 4.9Mhz or more. It comes in January.

The Ti has a larger memory bus 384-bit over 256 for the 1080 which may be an asset for the sim, if I remember well the discussions in the early FSX times, but it has a lower speed 1623 (boost clock) against 1733 for the 1080.  What is the most meaningful for P3D  ?
