how does an overclocked 980m compare to a 970?
Equal, if we're talking finding your max OC with a custom vBIOS.
Digital Foundry did a stock vs. stock comparison here.
Country: USA
Max Budget: 2000 USD
Max size: 15"
Planned usage: Gaming primarily on campus. Looking for something with a relatively small and thin foot print so it's easy to carry around so I do expect to pay a premium. Dell's new XPS Infinity Display line looks great but I'm looking for something with a 970m or 980m in it in order to be able to keep up with next years release schedule. Would also like a premium fit and finish since I'm used to lugging around a MBPr. I have a 27" iMac for heavy lifting so I'm good on that end.
"Relatively thin" would be the MSI GS60. Nice config here.
