Msi gt72 or clevo P375SM-A?

Hi, I'm after some advice please. I can't make up my mind which gaming laptop to get. A 17" msi gt72 which has got 16gb ram, gtx 980m 4gb, 120gb ssd and a 1tb hard drive for £1499, or a clevo p375sm-a 17" based laptop which has got 2 x gtx 970m 6gb in sli, 8gb ram and no ssd for £1570. I could add an ssd and more ram to the clevo unit but that'd bump the price up to nearer £1700. Which would be better long term? Any recommendations or advice would be greatly appreciated.

Thanks in advance...
