Ecc is usually a gen behind non ecc... So it has slower clock speed. It also uses more of its speed to process the ECC... So generally it's slower.
Ecc is good for certain things... But for a
sign shop, the premium on price isn't really worth it . If you need your
computer to be on 24/7, with almost zero risk of a corrupt file... It's worth it.
If you don't mind the occasional restart, or risk of (still almost zero) percent of a corrupt file.. non ecc works as well.
I have a server at home... Using a desktop mono/cpu, non ecc ram.. and it's been on for 7 months without a restart. Until I put
windows 10 on it... Now it restarts every other night for upgrades.
Ecc is only like 3% slower than normal ram, and it's not much higher in price. The additional cost comes fom a mobo/cpu that can use ecc ram. They're generally built.better, last longer, and are meant to be kept on 24/7, so some people like the piece of mind it gives.
Me.. I shuck 8tb external HDD and throw them into a 24/7 Nas for $100, instead of paying $300 for a hard drive designed for 24/7 use. Now if I was a company like Netflix, or one where a small corrupt file or system reboot would cost me thousands of dollars... I'd go for enterprise grade components.
And yes - even Photoshop / illustrator benefit more from a card designed for processing rather than gaming. Theres a new vega coming out that's great for cad/Photoshop/video editing, costs around $800... And if you try to game.on it, it'd perform like a $200 card .
There's so many different things that can affect the performance of your
computer for the application you want it for. If your techy, you can research what's best... If not, it's usually best to hire someone to design a system for you. You can spend half the price, and get the same if not better performance on a system made to do ripping / Photoshop editing.
To put it into perspective... I think the systems we built for our designers cost about the same, if not slightly lower than their monitors cost... Why build a awesome design station, then buy a cheap $200 monitor that has crappy color accuracy?
Just make sure your tech knows the specs. Ours was told to bring in a new
computer for our rip station... I got a 60gb ssd hard drive. 40 was filled with
windows 10... 5-10 with onyx... And that meant I couldn't rip anything because I ran out of space! I would have rather built.it myself, as a lot of the specs aren't optimized for what I use it for, sadly they bought it without even letting me know. So.. always research specs before committing!
