Meh those mushrooms are overrated.

I rather eat those whole chickens stuck inside walls in Castlevania.

Yes, that's what I was saying, but their meter of big enough is something that needs correcting. I came across this article where they were testing a Hardline on same rig with different graphic cards and after 5 they were locked out.

Off topic, isn't period used to signify full stop? I don't think you need to end your statement with another.

Can uninstalliing the games then reinstall after the hardward change negate the DRM?

Unfortunately, I haven't had experience with them myself but it would probably involve sending back the server your hardware stats along with the activation stuff so there's no workaround to it. Then again, I am just guessing based on how I would do it if I was in their position.

1. That's the last gen version you're talking about which had to fit on two DVDs in case of the Xbox 360 version and was identical in terms of content on the PS3 (thus had approximately two DVDs of data also on PS3). Of course the last gen version is much smaller than the next gen one which the PC version is based on. Keep in mind that just doubling the sharpness of a texture already means quadrupling its size.
2. About half of the game's content was streamed from disc during gameplay. The full size of the PS3 version is 17.2 GB.

Hardware Authentication is as broad a term as Car is. Usual (or most sensible) method is as follows:
1) You take some pieces of hardware from a machine and get a hash for them. GPU, CPU, Network Card, System Drive, Motherboard are the usual choices, though you can always use others as well. You store those hashes and a hash of them somewhere.
2) When you try to run the game, you check the hash of hashes against the current hash. If the hash is different, you check how many components have been changed, and weigh them accordingly. Changing the system drive may count as 0.5, while the GPU may count as 3.0, and the CPU as 1.5 for example. If the total changes are more than an imposed limit, assume it's a different machine and require reactivation.
3) Have a number of activations available, and a way to increase them. One method is to allow revoking an installation, thus getting back the activation, another method is to have a maximum number of activations left and gain some periodically, like Origin currently uses (5 machines limit, refreshed every 24 hours), or Anno 2070 which started with 5 activations, and would gain one per month, to a maximum of 10 activations (going from memory, may be inaccurate).

So, for a "normal" user that uses a few machines to play his games, and doesn't modify them every week, Hardware Checks are up to a mild annoyance. For a user that does benchmarks and runs the same game on multiple machines per day, Hardware Checks are extremely restrictive.

Then there are of course the "Any change requires reactivation, you have a total of 3" cases, which suck for both normal and weird users. No idea what GTAV will use though.
There was a thread here on GOG about it, but mostly people chose to ignore the Origin response. So, to add to this, Origin has a limit of 5 machines per 24 hours. If you wish to benchmark a game, thus use more machines, contact support and they will remove said limit. Tell me if you want me to dig up said thread or the response.

You mentioned Hardline locking people out for 24 hours, plenty of games lock people out permanently.

Shit.

And yes I already commented that this is the Next Gen PC version which is clearly even more demanding than the last gen console.

JMich, some of us want to play our games 5,10,15, 50 years down the line. But since we will have gone through many more than 5 hardware changes by then, plenty of games will be unplayable by then. Personally I have a desktop and two laptops.. 5 activations are easy to use up. These games are ticking time bombs. GTAV is even worse since it has that periodic entitlement verigication thing as well. Two reasons not to get it.

there is a super famicom game called life a life old fruity ;p

but yes personally i dont care about gta 5 or the series anymore either stopped caring ooooh several years ago

Actually most DRM have hardware authentication, Securom, Origin, uPlay, even Steam (try changing something significant on you computer while Steam is in offline mode and the next time you boot it will ask you to go online), so if you are willing to accept DRM then knowing whenever it uses hardware authentication or not is not really the issue, the real question is whenever or not there will be a limited number of activation.

I just got this computer exactly a year ago and I have not replaced any hardware on it since.

I assume my upgrade from 650 to 970 will be fine with no authentication issues because this is my first time doing this?

Which games does that? you can get them working again? there are ways to avoid this? (which is not being stuck with the same hardware forever)

It really depends how sensitive the algorithm is, I know Steam and Origin don't care about graphic card changes (at least the didn't last time I tried) but I have no idea about the one that GTA will use.

But still even if it's triggered by a graphic card change, you shouldn't have any issue unless you do it multiple times in a row.

Wait, that doesn't sound right...
