Reloop DJ 2 CE + Korg NANO KONTROL + sound card external

Hi,
I’d like know if I can use these three hardwares (Reloop DJ 2 CE + Korg NANO Kontrol + Behringer UCA202 ) in traktor pro 2,5 , without creating almost no latency.
My computer is HP Pavillion dv6 6055ep (Intel I3-2310M 2,1 GHz, 4GB ram, windows 7 64 bit’s, Radeon HD 6490M, 320 GB)
:confused:
