You need to modify the configuration on your main page and help page.  

When using ethminer there are two switches.  the -G you mention is only for AMD based GPUs best performance.
changing the -G to
-U is the configuration for Nvidia GPUs.  I think some NOOBs are confused by this.  This is only for use with ethminer and not with claymore.

Best nvidia GTX 1050/60/70/80 config is as follows

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

ethminer --farm-recheck 500 -U -F http://noobpool.com:8888/0x/ --cuda-parallel-hash 4
pause
all in a .bat file running windows 10 and latest drivers

the --farm-recheck at 200 milliseconds is quite low and I find it wasted network traffic.  I find 500 to 1000ms to be sufficient.  it can be increased to 1000 or 2000 which is 1 or 2 seconds check.  1 second check reduces bandwidth slightly minimizing submissions of stale shares"nonce". at 2000 you will get rejected shares in 24 hours.  I haven't at the 1000ms mark.

Statistically, new blocks are not once every second but mostly 10's of seconds so at 500 or 1000 milliseconds you don't miss much of new work.  Going out 2000 milliseconds gives you an accurate hash rate reported by ethminer, but risk rejected blocks.

I"m at 1000 and don't have any rejected blocks
