Zeus no, there arent that many.. lets see.. the oscars, the vma's, the ama's, the cma's, the daytime emmys, the primetime emmys, the tonys, the screen actors guild awards, the golden globes, the peoples choice awards, the blockbuster movie awards, the alma awards, the espy's, the bafta's.. oh my, i see your point... 

yes there are too many.. my apologies how about antec ne550m?


for many pcs, yes. for one in which you invested in a modern ryzen platform and a 2060? no.

you're cutting corners in the wrong place. for these specs, tier b on our housed psu tier list is the minimum i'd be comfortable with. it's really weird to pay extra to go from a 3600 to a 3600x -- or as steve burke noted in his review, you're paying $50 for a letter -- and then use an old, group-regulated psu.

https://forums.tomshardware.com/threads/psu-tier-list-psucultists.3624094/ no, that type of processor is soldered to the motherboard. it can never be replaced. no, the top one is not worth it.

the core i7 990x is a very expensive cpu that's ideal for hardcore number crunching, 3d design/rendering and media encoding. but it's not future-proof by any stretch of imagination, that socket is already obsolete.

for everyday use and gaming, the core i5 2500k is the best bang/buck processor on the market.

if you're building a rig for movie editing or working in maya/3d studio max/blender, you're probably still better off with the core i7 2600k than the 990x because of the huge price disparity. the $700 difference in price corresponds to a small difference in overall performance. for that money you could have a professional workstation graphics card, triple the ram etc.

for gaming, the most important component in your build is the graphics card, and i don't see one listed? roughly 70% of gaming performance is determined by your graphics card. for gaming, even a core i5 2400 with a radeon hd 6970 or gtx 570 is far superior to the more expensive 990x with some $110 graphics card like a radeon hd 5750 or geforce gts 450.

anyway, it's not possible to buy any computer hardware that will still be considered "great" 5+ years later. you want something great by today's standards, on a socket which provides good upgrade options a couple of years down the road. you may not need to upgrade so quickly, but you'd be able to- that's how you get a system to last 5+ years.

ivy bridge will be released in the next few months, and that will outperform sandy bridge. neither of them. much higher specs than you actually need. core i3 with 8 gb ddr ram and an ssd hd all for less than $500 should be more than enough for your uses. it is: 48 50 hz answer: k=7 which company?
