Does anyone have any pointers or personal experience of the benefits of a Titan amount of VRAM please? (Am wavering between the Titan or a 780Ti and the only real discernable difference apart from price is the 3Gb extra VRAM..?) Or would I be better getting one 780 now and another later? Cheers k

The later is what I did but that's all I can say...

 

At the moment there seems to be no reason for more then the 3GB because P3D2 is still 32 bit. But once it turns to be 64bit the extram RAM may make a difference.

What are the odds of you still using a current video card when P3D goes 64-bit?

You will probably get a more of a short term benefit if you go with two cards for surround if you have multiple monitors or SLI. SLI isn't supported yet, but it will be long before a 64bit version is released. SLI is being tested by LM now, though we don't have a specific release date from them yet. You can probably pick up a few 780's or some 680's cheaper.

32 bit has nothing to do with the graphics card memory. It only has to do with main memory and even that is per process. A 32 bit process can easily exceed 3gb graphics card memory utilixation

What's the resolution of your monitor? If it's 1920x1080 then 3GB is going to be plenty.

1920x1200 (x3)

1920x1200 (x3)

With 3 monitors go for 6 gb. I have read posts where 3gb has been exceeded with one monitor.

 

I run 3 monitors 1920x1080 and regularly exceed the memory on my GTX 680 2gb

 

Are you aware EVGA are about to release a GTX 780 with 6gb ram and hopefully a 780 ti with 6 gb later in the year.

 

Hope that helps

Titan is a good choice for 3 monitor setup ... v2.2 is actually off loading more work on the GPU than prior versions, so more GPU will help.  There is also the Titan X due out sometime this month (which "might" bring the price of the Titan down) and I think nVidia plan another new GPU end of this year or beginning of next year.

 

Also, have you considered AMD's offerings, two R9 290 (4GB each) cost about the same as one Titan and if Crossfire works in later versions of P3DV2.x you'll be in a good position ... I think.  I don't have first hand experience with the R9 290 but I did ask about it and oddly I couldn't get much input on how well it works with P3DV2.x.  Most seem to be using nVidia cards.

 

Cheers, Rob.

Thanks Rob, I had considered 2 R9 290s but leaned towards the NVidia offerings because there was simply more anecdotal evidence of them working well with P3D2 and I can't really afford to chance it... I'm only running a 2500K at 4.7 with 8Gb 1600 RAM so the GPU is only half of the equation in relation to this upgrade.

This is good news for my GTX 770 with 4gb.

Does anyone know how these quasi SLI cards like a 690 or Titan works in Prepar3D? Is it really 6 Gb VRAM or does the lack of SLI support means it's 3 Gb? As I believe these kinds of cards are like 2 cards slapped together?

 

Secondly I have heard especially with triple monitors that not only is VRAM important, where about 3 or 4 Gb is the minimum you want, but memory bus is a factor too (384 bit is important vs 256 bit cards to push through all that rendering quickly or something like that).

What?!! Gotta get me one of those when it's out. Did they say this year or the following?

Here is the link. Depending on price the ti will likely be my choice.

I think you mean the Titan X ... this is a single card running the equivalent of two Titan GPUs ... it's 12GB VRAM.  I believe the Titan X is not supposed to have some of the traditional bottlenecks you see in other Multi-GPU single card solutions ... hard to say until we see it released sometime this month ... it's about $3000 and I have no idea what supply will be like.  I might get one if I see some benefit over two single GPU Titan's in SLI.

 

FYI, a single Titan (single GPU) is 6GB VRAM.
