ssd, don`t think u use your optical drive in -100c.... and if u run it in -100c u probaly don have liquid cooling... or if u have you have some cemicals that does not turn into ice
if you run your pc in -100c don`t think it`s going to be a problem whats gonna break if u run it in a -100c enviorment? (enviorment or however it`s written, im norwegian)
on my current pc i have only upgraded it with a 2TB hdd, im getting another 780 after christmas maybe if i dont spend the money on a trip to my gf (she lives around 60 Kilometers away)
i ofthen play games while standing in my knees on a hard wooden foor if im gaming while having to take a shit. my knees starts to hurt after maybe 4 hours. (i dont wait to take a shit for 4 hours but i feel like im more consentrated while being on my knees gaming. in fact i am tanding on my knees as im typing this )
i play bf4 1080p ultra 70-100+ fps depending on the map (with a reference 780 and 4670k, not all that much difference) if u buy a 780 you know it`s gonna rape most of the games that`s out on the market...
let him come with a arguments and then you counter them all with your research knowledge! tell him to come with facts/arguments about why exactly why A is better than B.
looks verry good for gaming and amateur video editing. i wuld recomend you buying a little bigger ssd (maybe a 240gbssd) since they tend to fill up quickly at least for me. smart of you to get a 800w psu for future SLI. I think this will give you a lot of joy and good luck finging the best deals !
the msi geforce gtx 770 gaming 2gb is a great card, a friend of me have it and he is enjoying the card. (i wuld personally bottle up to a 780, but if the budget doesnt support that choice i understand)
