think this thread need update

just try my lucky for asking opinion here..

Nvidia 840M, how good its handle high setting games such as Dota2, CS:GO, Rome TW I, II.

how is the AMD Radeon R9 M280X vs Gtx 860m? i used to be AMD fans before but recently, due to unsatisfied user of GTX series and some nvdia gpu is under performance, i really have doubt with mobile gpu. since i already stick to my desktop, and mobile gpu is getting complex + i am outdated too. so far i understand that, nvdia gpu > and..

i like to consider this
Asus N551ZU-DM022H – 15.6” FHD / AMD QC FX-7600P / AMD Radeon R9 M280X
HP Pavilion 15-p036TX(Natural Silver) : 15.6” / i7-4510U / GT840M 2GB

and i saw this ATI VENUS XTX R9 M275 and AMD Radeon R9-M275.. same series, different architecture..

it was said that.. ATI VENUS XTX R9 M275 = GTX850m
