Unfortunately you get what you pay for. Everything is about compromising price and functionality/reliability. I have a Samsung gaming laptop NP-700G7C and am very pleased with it but it is not exactly the easiest thing to carry around.
Now the novatech laptop is priced without an OS (So it'll probably be closer to £750 with an OS)Now the screen on the MSI is 1920x1080 where the Novatech is 1366x768 (will there be a huge difference?), they both have Nvidia GT650M GPU but the novatech version is 2GB GDDR3 whereas the MSI is 2GB GDDR5 (is the MSI version the better version?).
The only one thing that the Novatech has that is different is a Hybrid HDD/SSD. If we're being honest is the hybrid going to be that much better? (I've heard with towers that they're good but I'm guessing you don't get much SSD on a hybrid in a laptop).
