Hi guys,

I'm wondering if you could help me with a question about my graphics cards.

At the minute I'm running three monitors, 2x dell 1920x1200 and I recently purchased the Samsun 28" 4k monitor. The three monitors are great and I'm also able to run Nvidia surround by dropping the 4k monitor down to 1920x1200. other than playing around with nvidia surround I'm mostly gaming on just the central monitor, the Samsung 4k. My pc has 16gb 1600mhz ram, 2500k OC to 4.8ghz, and 2x Nvidia Evga ACX 780ti GPUs. Before I purchased the 4k screen I had no problems running everything maxed out but since I've got the 4k screen I have obviously seen a fps dramatically drop. However I have noticed that looking at afterburner while gaming that often the cards aren't running at 100% and the VRAM on both cards is maxed out. I had a feeling the VRAM would get maxed out but is it throttling/ holding back my cards from a better performance ?

So obviously I don't want to sell my cards as I love my 780 ti cards as they are so blistering fast. I've looked at a few alternatives, mainly the new 780 with 6gb of ram. Would getting 2x 780 with 6gb of VRAM improve my frame rates considerably? Or is moving back a card regardless of VRAM not going to make much difference.

Ideally I'd like to just add an extra 780 ti (I have a asrock z77 designed for three cards ) rather than trying to sell my cards and get something else.

A couple of extra caveats. I wouldn't change to AMD as I do also a lot of editing film and photography and the cuda cores come in handy and secondly i could possibly update to 2x Titan cards if at a real push (the original titans not these silly 3 grand titans) but I know my cards are quicker than titans, but don't know if the extra VRAM would make a significant difference in performance.

So in essence should I just get another 780 to to push my fps back up to around 60 fps (I'm currently sitting at around 45/50fps on most games at 4k) or sell cards and look at the 780 6gb or possibly the titans only if it's really going to make a significance difference.

Thanks in advance for any advice

Adding more cards doesn't increase the memory since it's mirrored.

You should try overclocking your VRAM, that might help remove the bottleneck caused by it.

Not trying to increase VRAM by adding an extra 780ti. I'm aware VRAM doesn't double up. Just looking to improve fps. What program would you reccommend for OC the VRAM ? Evga precision?

Well you could also try overclocking the core, a third GTX 780Ti is a lot more expensive than overclocking.

MSI Afterburner is pretty good.

Hi neil,

I have the same issue when running 780s sli on 4k which is higher pixel count than the 3 screens you are running (I have the same samsung 4k). I think honestly in some games we are hitting the VRAM limit esp in games ported from consoles. Adding 1 more 780ti will not help with the VRAM issue but will accelerate other games/prog.

Solution?
1. Sell off the 780tis and buy the titan blacks..
2. Buy another 780ti and pray....
3. wait and pray...

Or jump ship to the RED team...

cheers
