Hi,

I've recently bought a second Titan black to use in sli, my benchmark on a single card was roughly 10000 on fire strike and now with a second card has only increased to roughly 12500ish. I'm running a i5 3570k on an asrock z77 extreme 4 MB with only 8gb 1600 ram, is this a reasonable increase or am I running in to a bottle neck somewhere? I'm aware that my second pcie card will only running at 8x is this slowing things up?

Any help welcome, thanks in advance

If you have MSI Afterburner, run GPU and CPU usage on the OSD when benchmarking (or gaming). If your GPU usage is lower than say 97-99% in usage and your CPU cores are maxing out at 99%, then you have a CPU bottleneck. If your GPU usage is maxed out and your CPU cores are lower than maxed out, you have a GPU bottleneck. You can also check this by running a GPU-Z window for each card and CPU-Z window and then set the GPU-Z monitoring "Sensors" tab items to monitor "Show Highest Reading" in the drop down arrow selections fro GPU load and whatever else you want to monitor like temps.
