Try to look for settings for your card in this thread:
https://bitcointalksearch.org/topic/the-big-vtc-vertcoin-settings-thread-416572
I know it's for Vertcoin, but since it is also an N-scrypt coin, the settings will be the same.
EXEcoin can be mined with vertminer 0.5.3 as well. I use the same settings and i get the same hashrate as i did with Vertcoin.
My Club3D and MSI 280X casrds will get approximately 345kh/s each with these settings:
GPU core 1000MHz, GPU mem 1500MHz
and:
"gpu-threads" : "2",
"intensity" : "13",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "8160",
