timppu: Ok then, I will stick to normal SO-DIMM DDR3 as that is what my laptop already has. Thanks for the clarification.

Avogadro6: I don't think this is the right time to buy a new rig, but someone can lend me their old pc: dual core 2.4GHZ, 4GB ram, Win7 64bit; I don't remember the name of the GPU, but it's something that'd barely run The Witcher 1...
So I was thinking to slap a new video card on it and maybe some more RAM, and use it until I decide to get a new PC (probably another year or so). Seeing as it's got only a 300w PSU, the choice is between a GT 1030 and an RX 550. I could also get a 1050 for 40€ more but I'm worried about the wattage, plus I imagine the CPU would bottleneck it badly anyway. That said, I have some doubts:

1) At the moment the GT 1030 seems the best choice, especially for the super low watt comsumption (20-30). Is there any reason to opt for a RX 550 instead? It seems to be slightly more powerful but it's more expensive, and the official AMD page recommends a 400w PSU minimum (even if it shouldn't use more than 50w at any time, so I guess a 300w PSU should be enough).

2) Most amazon reviews say the 1030 is a great 45€ card... and yeah, I imagine it is... except that now it's doubled in price everywhere. What the heck happened? Bitcoin miners?

3) Apparently at the end of the month Nvidia is launching its next gen GPU series... should I wait for that and hope that it'll make price drop a bit (or maybe better budget GPUs)?

4) I'm not clear on the exact power of the 1030. Most recent AAA games list the GTX 660 as minumum requirement so I compared them, and according to multiple sources the 1030 is quite weaker... and yet I read it's enough to play even TW3 at high settings. Could I run some recentish games with it? Obviously I'm not aiming for 4k 60fps fluff, but it'd be nice if it could run XCOM2, even at mid/low settings.

candesco: If you could barely run The Witcher 1 then my guess it's an old integrated videochip, something like an Intel GMA 3100 or even older. Cause i runned The Witcher when it came out then on a Pentium 4 2,66 Ghz Northwood, Radeon HD3650 silent, 2 GB DDRAM, Windows XP. Runned it at medium settings though, but it worked then. Even later on with the EE patch installed. So any low budget card would do the trick for at least The Witcher 1 and probably also 2. Keep in mind that the first The Witcher was released in 2007.
For newer games the standards are a bit higher.

As for the Gt 1030, it seems that Nvidia made a rerelase of that thing, but now with DDR4.

So if you go for that card, then watch out which one you buy and go for the one with GDDR5 instead, such as the Palit Gt1030. http://www.palit.com/palit/vgapro.php?id=2883&lang=en&pn=NE5103000646-1080F&tab=ga

timppu: And there is no disadvantage in mixing DDR3 and DDR3L in the same PC either?

Either way, I guess I will go with regular DDR3 204-pin, as that is what the PC has already. Now if I just knew if it is safe to buy about any memory brand. I don't know why I recognize pretty much just Kingston and Corsair, they seem to be the most common ones here at least in the stores I visit.

Tallima: I wouldn't touch it. You'll be upgrading with parts old enough that they start becoming rarer, warehoused parts, or you'll be putting in money that won't have much return.

I'd recommend buying a new full PC. Use yours until it's dead-dead. Maybe do a fresh install of your os to give it some more life.

PC parts are pretty cheap right now compared to the past few years because the memory shortage is gone. So if you have the money now, there are good deals to be had.

ariaspi: GT 1030 with DDR4

Avogadro6: I was just updating stuff, but the whole system just felt strangely slow. I don't know why but there's often an odd 1-2 seconds delay when I click on something. Maybe it's the HDD.

WinterSnowfall: You just named my two favorite RAM memory module manufacturers, so there you go :P. I'm currently packing Corsairs, but Kingston is a good alternative - their high performance HyperX modules are also good, but the infinitely small increase in performance they provide compared to other manufacturers is usually not worth the extra cost (unless you're trying to beat someone else's PC benchmark scores or what not).

Avogadro6: Is there any reason to opt for a RX 550 instead?

timppu: I saw in Ebay some selling e.g. Samsung for a good price. Is it a good brand too (if I am merely after normal 4GB DDR3 1600MHz SO-DIMM)?
