I'm going to buy the sp4 but before that i have to question for you guys ! First of all, i have found a good offert from a local reseller for the i5 4gb ram version, well ... will it be enought ? I'm pretty worried that 4gb for today's app simply won't be enought , what do you think ? What about the fan ? I have to expect to hear it while watching a videostream "twitch, popcorntime" or during daily browsing ? I'll be able to play some light game on it ? Like binding of isaac, enter the gungeon etc ?
