Graphics Card for Dell OptiPlex 3040 SFF

Yes, or the RX6500, which is even better and very similar in design to the RX6400. It's just that they are 64-bit and PCIe 4.0x4 or x8 instead of x16 (x16 is for high-end graphics cards in general). Normally, there is also the RX7500 in RDNA3, which is even better designed but similar. But I don't know if it's available here. But it definitely reaches at least the level of the GTX1650ti and even the 1660 (and it's better than the 1060).

Moreover, you can find them in passive versions (without fans), or non-passive versions where you can remove the fans without causing major issues. If there is a small space for a fan in the case nearby, just adding one will help the air flow out a bit more without taking up too much space.

But in any case, you should absolutely not get a 1030 or even a 1050; they are total garbage. Even a GTX970 4Gb will be much more performant, or an RX560 4Gb from AMD Radeon.

I would have recommended the RTX3050 4Gb (preferably the 8Gb of course). But I've received very negative feedback on these 3050s; they are useless, even at 1080p it's impossible to play on Ultra, so they follow the path of NVIDIA's x50/xx50; always junk...

Of course you can add a graphics card since there isn't one already installed (the Intel HD graphics chip is just integrated into the Intel CPU to turn on your screen and thus provide display without needing a graphics card; unfortunately, Intel chips are not very powerful so you won't be able to play games with it, but you already understood that). You just need to have space in the case and then check the dimensions against the graphics card you want to add. As we can see, you have the PCIe 3.0 x16 slot empty; this is the location for a graphics card or other PCI-EXPRESS supports like special SSD-NVMe storage cards, which can allow you to add 1 to 6 NVMe (M2) SSD slots; it's like an adapter that works for many things, you can also add a Wi-Fi+BT card with a few additional USB ports, etc. But anyway, that's not the topic. Logically, if you look hard enough, I would recommend the RX6400/6500 or more recently the RX7500. They won't have amazing performance, but they'll always be better than the budget rubbish from NVIDIA. (With a bit of luck, you might still find RX560/560D online, which have the advantage of being very small). And they also have the advantage of being low profile (consume very little and don't necessarily require fans; you should see if you can find passive versions, or you can remove the fans and just leave the plate under the fans that serves for good cooling. And you can, for example, put a small fan in the case facing the right direction not far from the graphics card if there's space; this will help to expel excess heat. But anyway, aim for at least an RX6500 if you want to game at least at 1080p at 60 to 90fps (so a 60Hz to 90Hz maximum screen). You have an i7 7700HQ, so if it's at least a 4Core, it should be sufficient to enjoy quite a few games. Certainly not the most demanding and recent ones, but it will get the job done. Moreover, you might even change the CPU to a slightly more powerful version than the 7700HQ, but that's to be checked. I also have a mini Optiplex 3040 (even smaller than yours) on an LGQ1151 socket; I have a dual-core Pentium in it but I know I can put an i3/i5/i7 in there. Just search your PC's model number online, and you'll quickly see that it's compatible with quite a few CPUs, even if I think that in this range, the 7700HQ is among the most powerful, but you never know. And I’m silly, of course you can change the processor; we can see it clearly in the picture, I had forgotten. You can often put 2 generations of CPUs per motherboard, so maybe you can upgrade to an 8700 for example (or a 6700). But anyway, choose the most powerful from the list and used ones cost very little these days. I once got an Intel Core i7 3770K for barely 40 euros (PC version, so more expensive than on mini PCs like the Optiplex). You’ll see, there’s plenty of choice. And for the graphics card, if the case isn't suitable or too small, special PCIe extenders exist, then you connect your graphics card to it. Just make sure nothing can get caught in the fans or anything else, and you're good to go (like securing it next to the case or on the case, it depends on where the PCIe port is located). Otherwise, there are also external graphics cards specially designed for PCs that don't have a graphics card and don't have the suitable slot, but they are much more expensive unless by chance you find a used version. You check the max consumption of the graphics card; if your PC handles a maximum of 180W, you take a graphics card like the RX6500 which will consume a maximum of 150 to 200W (in summary, even if it says 200/230W, the card doesn’t actually consume those 200/230W; it’s under extreme testing that you might reach maximum power (so avoid stress testing with benchmarks like OCCT, for example). There you go!

Don't listen to the noobs who tell you that you already have a graphics card because you have an Intel HD530 lol; this is not a graphics card at all, it's like I said, an iGPU (in the same chip as the processor, that's all, and it's for people who don't necessarily have a graphics card and don't game; it allows you to turn on your screen). A CPU without an iGP cannot turn on your screen, so it won't start, so you have to put a graphics card in. For example, with an AMD Ryzen 5600X, there’s no iGP chip in it, unlike the Ryzen 5600G which does have an integrated chip, but it's insufficient for gaming; it's just for backup. After I see that your motherboard has a power connection, so nothing prevents you from adding a more powerful power supply, for example, 400W with 80+ (always the 80+ label is to certify it actually does 400W); you can put everything in another larger case even if it's not necessarily pretty, but there you can add whatever you want. But if you want to stay in the same case, you can also find a more powerful power supply but with the same dimensions, to then put a more powerful graphics card like the RX6600XT or the RTX3060, for example. But beware, starting from the RX6600/7600XT // RTX3060/4060, they are much larger. So it's up to you because we don't know the size of your case and we don’t know if there’s a slot at the back of the case for a future graphics card. On my Optiplex, there’s no slot, so I already know that I'll have to leave the case open or change cases.

PS: Don't forget that the biggest drawback of the iGPU chips integrated into the processor (CPU) shares the RAM DDR3 or DDR4 of the PC, so you don't have VRAM in GDDR5/GDDR6, etc. This makes the iGP even less efficient. By the way, if you buy a cheap old graphics card, be sure to check that it has VRAM in GDDR5 or GDDR6, so don't buy the rubbish that has plain DDR3 like on the old GT710/730/1030 (some 1030 will indeed have GDDR5 but you have to make sure it has the "G" in front of DDR). Otherwise, you're just going to replace it with the equivalent of the iGP of the processors, which has no interest and you won't be able to play. Except Candy Crush and Solitaire! ^^/

I grant you that, but I don't know which graphics card can be installed with the one already in place.

At the same time, it's normal; the GTX 1030 and 1050/1050 Ti are not really made for gaming, much like the RX 450 and 460 from AMD Radeon of the same era (except maybe the RX 460 4GB was a bit more powerful than the 1050 Ti). But generally speaking, all the versions that end with 50 from NVIDIA are low-end, barely capable of playing properly at 720p maximum (1080p@max 60fps for the RTX 3050 4GB, you needed at least 8GB otherwise it's worthless). Much more interesting on the AMD side, and they can also be installed on mini PCIe ports in x4 or even x8 (instead of the standard large format in x16), which were the RX 6400 and 6500, significantly more powerful than the 1050 Ti/3050 4GB, and as a bonus, they are low profile (no need for fans, knowing that there is also the 0db mode that automatically disables the GPU fans). There’s also the RX 7500 more recently (logically, there should have also been the 7400 but not necessarily for sale here in France). Same, it's perfect for low profile gaming on a 1080p (FHD) display up to 60/90fps (so a 60Hz to 90Hz screen is enough; on a 120Hz, it's not powerful enough except for a few older video games, of course).
