(UK) Can you trust CEX? Buying USED CPUs

xFeaRDom · Oct 12, 2016

Hi Community,

As I have recently decided upon upgrading my build, I have found a National company (No clue if it is available in different countries), known as CEX, which sells used Electronics, games, CDs etc.

I am just wondering if any of you have had any experience in buying from this company, as I may try out their process when it comes to buying a processor, looking at the 6700K, I can get it for the same price as a brand new 6600K, and it has many good reviews on lots of different devices, which makes me lead to believe that they are trusted and successfully assist any customers etc.

There is also a 14 days return policy if you change your mind, a 30 day policy for a full refund if it doesn't work in the first 30 days, and a 2 Year warranty on everything but things like batteries.

Just wondering if I should trust them, as I can always return it for a full refund if a fault develops in the first 30 days, so I can basically stress test it in the first 30 days, and if it develops a fault or stops working I can just get my money back and buy a brand new 6600K.

Or would it be better just to buy a brand new 6600K? As in the 2 years if it breaks, then I can just get a replacement.

Looking at the specs you are listing in your sig I think you'll be disappointed by the performance difference moving from a 4590 to a 6700k if your main use is gaming. Personally I'd hold fire upgrading right now, the 6700K isn't really much faster in real terms.

As for buying from CEX, I haven't purchased directly from them, although second hand components are usually safe enough- and 30 days is plenty of time to ascertain if the part is ok or not. To be honest CPU's are pretty reliable unless you really overclock them hard- although remember if you OC it you invalidate your warranty anyway- so there's no advantage to new there.

I'm not doing the upgrade primarily for the performance, it's more of the aspect that my Motherboard is on its way out slowly, where little hiccups happen every now and then, such as I can't edit the overclock or change the fan speeds on my GPU without having to reseat my GPU, and after that it works perfectly, not sure if this is primarily an issue with my motherboard as it is, but I seem to get some issues with it anyways.

The performance wise, my computer is getting quite slow compared to what it used to be, and I do a lot of heavy-usage tasks, which is why I wanted the 6700K for the 8 threads over the 4 I currently have.

Not really trusting my MoBo as it is, so that's the primary reason for wanting to upgrade. Overclocking isn't really major but I'd like the ability to do so in the future if it starts slowing down, I doubt it though. For the first 30 days ish, I will just test it to see if there's any buffers or issues that seem to come from the CPU.

Ah yeah the i7 makes sense then. I'm not really sure what to say- you do have more comeback on a new part though. I guess when your looking at stuff this new and pricey I'd personally be tempted to pay the extra and get new. I quite like second hand parts for a budget build, but I'd be more interested in buying something like your current cpu at a good price if that's what I'm doing. You have to wonder how / why a 6700k has ended up as 'second hand' already? It's normal to upgrade from something a few generations old, something that's still current though?

That's a fair point on why it would have been sold on second hand, but surely they've stress tested it and probably done a basic overclock to ensure that it works correctly, as they don't pay you until they've tested it. I know it's not essential for me to upgrade as of now, my system is perfectly fine and probably is a waste of money to upgrade. Not really planning on doing it now, probably in a few months, some time after Christmas and I'll see if I can get a good deal on brand new CPU.

Yeah I'm not sure what testing CEX do. I don't think there's a specific issue with them, I'm just curious how a 6700K winds up there- thinking logically it's probably a result of someone buying an upgrade they couldn't really afford so had to get some cash back on it quick. One plus point is you know it can't have been used for very long

Yeah it's a fair point, I guess the warranty and 30 days return guarantee provides some comfort, as if someone over-overclocked it

and partially killed it, it'll show it within the first attempts that it has done so. And yeah, it's probably there because someone needed ££££ quick. I guess it can't be too bad then.

I'm going to save the link to it on my phone just for future cases, it's fine as it is as I barely use anything intensive so nothing gets stressed, but that's because I work longer hours and obviously the girlfriend needs most of the spare time I have :lol:

Might also wait and see what the 7700K is like when it is released, or the 7600K, guessing that's the i5's name

Depending on the price, it might be worth it. As the 10nm process will be interesting, and will probably raise the prices slightly.

The 10nm Intel processors won't be around for a while, not sure what the naming is but the new ones due soon are just tweaked version of the current SkyLake cpu's and are still 14nm. Either way if you can wait on a cpu upgrade there will always be something newer / better coming out

Also worth keeping in mind that early next year we should finally see what AMD has with it's new Zen cpus- from what we've been hearing it looks like the new Zen processors should sit in between Intels mainstream and high end platforms, which could be quite interesting (and if nothing else might prompt Intel to offer more cores lower down the stack, I could see the top mainstream part being bumped up to a hex core / 12 thread part for example).

That's a fair point, was just expecting the 7700K to be 10nm (as said if you search it) but hey, I forgot about Zen, not really been down the AMD route before, as this is my first upgrade processor/mobo wise, after having this computer for 3 years this Christmas

I have had my fair use out of it. But depending when Zen comes out, hopefully this year like the 7th Generation processors, if it seems to have improved as much as they are bragging, then it may be worth a switch to them, and test that out. Got nothing against AMD at the moment, I just know that Intel are on top altogether with their stronger cores. But they're for mostly high-end gamers and computers.
