Generally I have noticed that computers with Intel processors crash less often. Once again, I know this only from the practical experience I have had. I may be wrong.
You've been an "IT guy" for four years. How often do system crash in your vicinity? I haven't had computers crash regularly on me since XP SP1 or so. If they do crash, do you keep a log? Do you investigate how and why? If you can blame the CPU (more likely the chipset), do you keep a note of that?
I don't know what to tell you, my practical experience is a 500 watt power supply can cause stability issues in a gaming machine.
A 1000w PSU can also cause instability. Shitty power supplies are shitty, no matter what number was printed on them.
but I still think spending $20 extra to get a better PSU than you need is a good idea.
550w is already better than the OP needs. He would get away with a *good* 400w PSU, I can guarantee this.
Rather than telling someone to look for the number on the label, it would be better to recommend them to buy a PSU from Seasonic, Corsair (mostly relabeled Seasonic anyway), Enermax, Super Flower or Antec.
It might be that there is more physical space to search on the disk and and as the part slows down with age it is more noticeable. It might be that larger drives over heat more easily (and therefore wear down more quickly) because they has more disks spinning. It might be that larger drives have more parts and are therefore more likely to have a single part wear out in the same space of time. Once again, I don't know what causes this
So how did you notice that? In your four years of IT experience, did you benchmark new drives and then kept logging their performance over time, always observing usage patterns, and then compare the data of larger drives with data of smaller drives?
Or is it more "Hm, this 2 TB drive seems slow and I noticed that Steve's 2 TB is slow too... must be something about big drives then"
I suppose I could just be really unlucky and I got 3 lemons in a row. or maybe you were really lucky and got the best parts in the lot. How often do you replace your cards? I tend to build an entire new computer every couple of years and pass my current rig onto my wife or a friend, so parts never get replaced until they fail. It might just be that you never keep a card long enough for it to fail.
I don't know, I keep my PC running all the time, if I game, it's long hours, I've build a cute little Small Form Factor System that most people would believe is impossible to assemble due to its size.
Lian Li PC-Q07 case w/ "minor" casemodding, Intel i5-2500k w/ Corsair H60 watercooling, GeForce 560 Ti w/ aftermarket cooling (Thermalright Shaman), Silverstone ST450SF psu.
Everybody tells me it must be running hot (it isn't) and that the 450w PSU can't power it hardware (it can). Build it in March 2011.
I've got a lot of experience in building system against "conventional wisdom" - which is mostly build upon web forum dogma. I've modded fanned PSUs for fanless operation, build my first watercooled system Christmas '01, when radiators were industrial parts and pumps were for aquariums.
The PSU hype started in 1999, when AMD recommended 300w PSUs for their then new Athlons. That was at a time, when PCs had 150w PSUs. They did it for the same reason that nVidia is recommending 750w PSUs for basically any gaming grade card: there are shitty power supplies out there and chances are that even a shitty 750w PSU will deliver 300w stably.
That doesn't mean we should be telling people to get shitty 750w PSUs, we should tell'em to get quality 500w PSUs.
I keep my hardware around for 2-3 years, then I pass it to my brother, then he passes it to my parents. The oldest system around was my 2006 rig (oc'ed Core 2 Duo, Radeon X1950XT). It was replaced two weeks ago with an Asus Nettop, since it was overkill for my parents and drew a shitload of juice.
Honestly, if hardware fails after 4 years or so, I wouldn't care, since it would be relatively worthless anyway. A PC is not a car.
Still, I had one motherboard fail me, and one hard disk. In 15 years of building PCs.
If RADEON (!) cards would fail all the time, don't you think that would have made the rounds by now? I mean, there are just two manufacturers out there (that matter), if one was producing 50% lemons, it should have come up.
