One more thing i like to point out, if possible, try to get from Gentech as Gentech could upgrade your BIOS and vBIOS for you before they ship to you. Saves you a lot of trouble when you get your laptop and got GSOD the first time.
I did request Ken last time, and Ken happily told me they could do that for you.
If i havent found a similarly priced G73JH-FHD with dual Momentus XT and im not in Australia, i will still go back to Gentech. No fun getting taxed when im getting my laptop delivered to me from US as i might need to spend RM1000 to get my laptop back. Or the customs probably gonna have lots of fun gaming time on my G73.
Another plus point is, go for custom thermal paste as stock G73JH paste are quite bad in most cases. Im considered lucky to have Fur Mark running lower than 90C, or maybe i didnt push it far enough.

Lastly, if you are getting a G73, i think G73JW would be a better choice. nVidia have better driver support and you dont get weird GSOD with nVidia. Forget about the infamous 8600M GT or 8400M GS problem, as it's probably wont happen again. Heard JW runs slightly cooler too due to better stock pasting, despite losing about 5fps to 5870.
