So currently I have a Dell Precision M6500 with an I5-520m/Firepro M7820/ 5gb and i was looking at my upgrade options new whole laptop or desktop 4+ core cpu. So I have what about 16 hours to render more complex 3d models that are 1.7gb which holds me back just for one pic in 8k res.And other smaller files which are 400mb takes about 2hrs.So I need a good rendering cpu to scale them down to minutes and be able to do other stuff on my computer. But my main problem upgrading to new modern high end laptop is price and only 1080p 17inch screens which I have 1200p screen and that won't be an upgade. And upgrading my cpu to an i7 is price to proformance is not worth it plus a lower battery life. And final option is desktop which I prefer a matx size between i5-5000 series/i7- 5000 series/ and xeon I won't be getting this now, maybe next year BTW I do some gaming (gta iv enb seies with lots of mods)(gta v and farcry3)
