Can this gaming laptop handle MOST games on ultra settings?

[Lemontarts]

I purchased MSI Gaming laptop on eBay and I was wondering if it's a decent gaming laptop or not. I know it is (I think) but I want to get some feedback from you guys. Also, can these specs handle most games on high settings? Also, what can I upgrade in the future? I know I can upgrade my hardrive, but I'm not sure. If yes what shall I upgrade and what shall I get? (I'm noob when it comes to tech)

Really appreciated.
Thanks

no, you can expect a 770m around ~15% slower than a desktop 660, i think you can look it up yourself what you can expect
it is actually a decent gaming laptop, but you can never expect desktop performance from a laptop.

Thanks, but what website do you use to check that the 770m is 15% slower than the 660?

770M is a decent enough card. You can expect to play games like Crysis in high settings if not Ultra.
