What settings did he change?
Try booting without the GPU.

It is assembly language.
Assembly for an accumulator machine (which is terrible) with 5 instructions (which is terrible) and special "registers" with insane blocking behaviour (which is terrible), but it is assembly. All rules on how to write good asm code apply.
In terms of the puzzle aspect it's basically Spacechem 2.0 and holy shit are 3 save slots a godsent.
10/10 would recommend.

Well the first Vega card was released, but you can't afford it. Performance is looking good though, so it might be worth waiting another month for the normal cards.
"Future proofing" doesn't really work. There's also the problem that either you can buy a high clocked quad core or a lower clocked 6/8 core. The 6/8 core would be more "future proof" but slightly slower in everything except streaming right now and more expensive. You could wait for Intel's desktop 6 cores, which should have a bit higher clockrates than the HEDT ones, but that's August or September and no idea about the prices either.
Or go with Ryzen, much cheaper, but again, a bit slower when you can't use 6/8 cores.

About the monitors: For 120/144 you can get IPS panels that are about as fast (just not 165/180/240 Hz), but they'll cost about 4 times as much as a TN panel.

XL2411Z (or BenQ Zowie XL2411, identical) for Lightboost / ULMB / BenQ Blur Reduction Utility, G2460PF for FreeSync.

Brother's friend:
I hope the prices didn't change too much. Generally I try to make partlists less than a week before ordering for that reason.
Can't blame him for waiting until after the exams though, getting a new pc right before that surely wouldn't have helped his grades.

Father:
Yes, 100£ more can definitely be put to good use here.
Keep in mind that the SSD also needs a slot, but fits in the bottom slot even with a 200mm GPU installed and the top slot is completely unaffected. So the external/5.25" bays still would've had room for more. The HDD bracket does complicate the assembly though, so I would've done the same with the added budget.

The 850 Evo is a bit faster than the SL308. I have no idea why the 500GB version is cheaper than the SL308 500GB, but definitely would've made the same choice.

Is he going to use the USB 3.0 ports on top of the case or rather the USB 3.0 ports at the front that the card reader will provide? A mobo with 2 interal USB 3.0 headers will fit neither the budget nor the case. So he'll have to choose which ports will be connected. If he's fine with using the case's own ports at the top he can save a few quid and get the version of the card reader without the additional USB 3.0 ports.

On that note, an upgrade to a mobo with 4 RAM slots is within budget and makes adding additional RAM later possible. I chose the ASRock B350M Pro4 because it comes with 2 PCIe x16 slots instead of one and angled SATA connectors are a blessing for cable management. However there's only 4 of them (instead of the usual 6, instead there's 2 M.2 slots instead of 1) so if your father plans on using more than 4 SSDs/HDDs with none of them using M.2 slots the Asus Prime B350M-A might be the better choice.

RAM prices changed so I was able to replace that with something cheaper and faster.

Well I don't think the speaker manufacturer knows the mobo's beep codes.
Also what your speakers do is rather irrelevant. Only the beeps coming from the mobo itself matter.

The mobo can be completely dead and still provide power to USB. The mobo is not a PSU, all it "does" is connect a +5V pin on its own power connector to the +5V connector on each USB port.

These changes seem to be the result of actual thinking and make sense.
Who kidnappend the TF2 dev team?

Update: He just +fragged his own post and -fragged everyone else.

Yes, but you deleted everything instead of just what's wrong because you have no idea what's correct.
Yet until you were called out on it you claimed this was the best config ever.

If you want to play around with bullshit server setting that's fine, but it's got no business being in a client graphics config.

Also why would anyone here want a config that's optimized to get the best hitreg with lmaobox?

Btw, why the new account? Got VAC banned or couldn't handle the -frags?

Do you get a lag spike, a freeze or an fps drop?

cl_showfps 2 will show you min/max fps.

That's not how it works.
You always have input lag.
Constant fps just keep it constant. Otherwise it'll be randomly spiking and dropping, which will fuck your aim up.

It does though. Some people are actually using this config when it's clearly worse than those he copied from.
We tried to give feedback, asked why the fps cap was set to 148 and his reaction was to delete all of his posts.

If he wants to mess with his own cfg that's fine, but he shouldn't post it and then claim some settings do all sorts of magical things.

All settings are either copied from better configs, useless/nonexistent/server variables or just straight up random values.

The first and last time that was pointed out felik deleted all of his posts and quit posting on the forum after embarrassing himself some more.

How is anyone still taking this cfg seriously?

Impossible to set up?
If you complain about contrast why would you recommend a monitor with even worse contrast?

Same reviewer, so you can't complain the measurement is different:

Either you're doing something wrong or you're expecting too much from a 144 Hz TN panel.

#2352
Wait why did you get it if you don't have DVI?

VG248QE is old and mediocre at best to outright bad these days.
XL2420Z is outdated and I don't see any real advantage over the XL2411Z.
Why not the BenQ XL2411Z, now sold as BenQ Zowie XL2411?
What are you looking for anything? Just 144Hz? Lightboost/ULMB? G-Sync/Freesync?
