~$350 "Newish" Build for friend

Best wishes for your friend.

How old is him? Wouldn't a Nintendo Switch be a valid option and wait till they can afford a more powerful system that will last them more than a couple of years?

First of all, best wishes to your friend.

Second, if you are in the US, Windows 10 Education isn't that difficult to legally obtain for $0-$10 if you're a student. And it's better than Home/Pro anyway.

Few other points:
-This power supply is a bit cheaper and better: https://www.bhphotovideo.com/c/product/1360176-REG/evga_100_bt_0450_k1_450bt_450w_80_plus.html
-You can possibly save a few bucks on the case as well. Newegg, in particular has cases under $20 after rebate that aren't really any worse than that one. I got one for free after rebate once.
-The G4400 does not have hyperthreading, and some games become problematic if they detect fewer than four threads. If you save on the power supply and case, you should be able to upgrade to a G4560, which has hyperthreading It won't bottleneck a 1050Ti, (it's actually good enough for up to a 1080) and the two extra threads definitely help.
-Windows 10 is kind of annoying without an SSD, and you can get one for like $50 if you've got room in the budget.

Edit: Sorry, didn't see that your power supply had a rebate as well. So the one I linked to is only a few dollars cheaper, but it's still better. And with regards to the SSD, you don't have to get one, but they're worth it if they're in budget.

Edit 2: Also, if you have a Micro Center nearby (again, if you're in the US), a G4560 is $57: http://www.microcenter.com/product/477030/g4560_350ghz_kaby_lake. Otherwise, you can get it from B&H for $79. I'm bringing this up because PCPartPicker lists it as $99, and it's not the best at finding good deals.

Maybe not very helpful for your case but check this video out https://www.youtube.com/watch?v=eHVO-eSV1FY

The channel has a lot of tips to run games on weak computers and laptops and the tips even work for stronger gaming PCs https://www.youtube.com/watch?v=I14HQ2LnoQI

case exceptions; can you not repurpose the case that he already has to save $30?

Try to get the G4560, the hyperthreading is a massive boost. However, you may need to update the BIOS on that H110 motherboard, for which you'll need an older CPU. Other than that everything else seems okay.

And as it is already said, pirate the damn Windows. I know it's not a popular thing to say in these forums but taking into account the tiny budget, it would be the way to go for me.

i was wondering since i bought a win 10 key for 5 bucks from a chinese guy just last week. but i seem to recall that selling off oem keys is not considered legal in most places.

after a little research it seems to me that a used gtx 770 is about half the price of and even faster than a new gtx 1050.

Any chance you can reuse the RAM from the old computer? May not be enough for what you want but if it's DDR4 you could still use it.

im going to waste 920€ on
average motherboard for around 70-100€
8gb ram
1050 ti
700 w
i5 7400
(normal case of 30€)
120€ monitor
mouse + qwerty
and one cooler,
1tb hdd and+ 250 ssd
plus the montage, all of this goes to 920€
what im doing bad? need help because im buying it in 2 days.

Do i really need all of this for playing or i can get something extremelly more cheaper?

Thanks for all of the replies everyone!

I want to reiterate, I already have a copy of Windows 10 so no need to pirate or purchase it anybody.

@carefree the RAM in the old comp is DDR3 so it is not compatible, good suggestion though.

@euroboardsgames repurposing the old case is a great idea that I had not considered. I think I will order all of the parts, including a new case, but clean up the old case while I am at it. Then assemble everything in the old case and see how it looks and if I like it just return the new one. Thanks for the that!

@Azone you're really putting me to shame here, haha. An obvious better PSU, me not realizing that the 4400 did not have hyperthreading, cheaper prices, you've got it all. Thank you so much.

So everyone thinks the 4560 will be a sufficient processor for the next couple of years? Obviously we aren't talking max settings or even medium, but playable at steady frames.
