It's the jump from the 7xx to 8xx/9xx. The prices went crazy for no apparent good reason apart from "Let's see how much these suckers are willing to pay". It's industry-wide for laptops, so it's probably nVidia jacking up prices since AMD's so far behind in notebook graphics right now. What that means is that you will see similar price jumps of about RM 1k no matter what the brand.

Aha! A good excuse to upgrade now!

All seriousness, though, yeah, prices will go up. Don't think tech is on the zero GST list, and tech usually has VAT/GST applied to it overseas too. That's not even taking into account unscrupulous sellers who will use the GST as an excuse to increase prices anyway under the excuse of "covering nthe tax charge". Sheeeeeee-it.
