Tried already at no avail. Disabled everything in the "Network Adapters" section, just to be sure . I mentioned the card reader because I had read somewhere that in rare cases it could be the culprit.

Oops, you're right. Just added them now! Apart from the ones I mentioned in the specs, the laptop also comes with a card reader and bluetooth module. I got my bluetooth module disabled, but I'm not really sure on how to disable the card reader (can't find anything in device manager)...

I used both LatencyMon and xperf which gave me similar results. I tried DPC Latency Checker as well out of curiosity (since they say it doesn't work well on windows 8) and it shows a much worse situation (constant 1ms DPC latency at least, with occasional 5ms spikes).
