With my R9 290 i cannot seem to get any higher rate than around 7000 to 8000 Khash. Seems kind of low to me

.
Somebody got a clue on how to get a better rate? I tried to play around with the -s parameter, but doesnt realy affect the hashrate.
To be complete:
Intel i5 4670K, 16GB memory, Win 8.1 X64

That looks fairly decent. Do you happen to know your card's clock speeds?
Check GPUz while the miner is running:
http://www.techpowerup.com/gpuz/I found out the hard way that cgminer never reset my clock speeds so the memory was badly un-derclocked. It ended up cutting my hash speed in half.
