It's not that he needs one, he's selling his old PC(current worth on eBay is ~£900, which means his current m.2 will be going bye bye So a new m.2 is going to be needed anyway, and personally, I think that if buying new, might as well get the latest tech, one day Gen5 m.2 will be mainstream and cheaper for big drives
as for price, the cheapest in stock 2TB gen4 is £105.95, (2TB m.2 seemingly being the sweet spot while a 1TB gen5 is only £87.95 that seems that's a no brainer to me, £20 less for fastest possible boot drive, if the motherboard was significantly more expensive than it is then, I'd maybe think twice about it, but right now a bare bones system without epic lian li infinity fans, is only looking at£374, but he will get his own expensive fans with his own paycheck, and I'll get the 9800, and ram when I'm flush again, on the 12th, plus I can write this off as his Xmas present, and be richer come December, he is eager to build another PC from scratch, I made him build his current one with my tutelage, and he wants to go full whack epic lian li build like all the pros seem to have atm, awsome looking builds
