Guys I am looking at this card...

EVGA GeForce GTX 780 SC ACX Superclock 6144MB GDDR5 PCI-Express Graphics Card (06G-P4-3787-KR)

 

I am getting it right?, because this is a £500 investment

Richard and Ryan say they push their 6GB cards past 3GB so the larger card makes practical sense. Well, I've got an EVGA 780/6GB card and my testing shows I never use more than 2.4GB and generally no more than 2GB. I'm wondering what might be the bottleneck?

 

I run 3- 23 inch monitors in nVidia Surround at 5880 x 1080. I have an i7 4790 multi-threaded and overclocked to 4.6GHz and 8GB of 2400 Ram. My temps are well under control.

 

I run P3D v2.3 with settings similar to what Rob uses for his 4k monitor setup. So I am pushing the envelope when it comes to making demands on my video card. So why is so little of my 6GB of memory being used? Is my CPU just not up to the task? My principal problem is with frame rates in the San Francisco Bay Area using Orbx NCA. I also have problems with NYC X v1.2. Otherwise all seems ok.

 

Thanks for any input.

If you are running a single 1080/1200p res monitor and consider 3GB of memory enough, then you can now pick up a GTX780 for under £300 GBP at OcUK... quite tempted myself http://www.overclockers.co.uk/showproduct.php?prodid=GX-044-KF&groupid=701&catid=1914&subcat=1341

in p3d 2.3 i haven't been able to max my gpu past 2 gig and i have almost all sliders maxed out, but if the price is close to each other the 6 gig would be the obvious choice.
