Used computer (GPU) advice
« on: October 16, 2019, 08:58:35 PM »
OK, so the boy saved his money up and bought a HTC VIVE. virtual reality set up. The one thing he didn't do was check to see it would be compatible with his computer (Alienware Alpha). It's not.  :P The Alpha has a built in GPU that cannot be upgraded and from what I read the refresh rate will not work with the VIVE.

It looks like he needs to get a gaming PC and he will definitely be in the used market. Any idea what a cheap used setup would cost? Below is a list of recommended GPU cards for the VIVE so would be looking for a setup with one of these.

From this list what would the "bargain" GPU be?

NVIDIA™ GeForce RTX 2080 Ti | 2080 Super | 2080 | 2070 Super | 2070 | 2060 Super | 2060
NVIDIA™ GeForce GTX 1080Ti | 1080 | 1070 | 1070Ti | 1060

I don't think that there are really any bargains per se, it's really more of a situation where each one slots into it's level of performance vs. $$$.

With VR you want as much horsepower as possible, you're rendering 2 relatively high-resolution images at the same time, and you want that to still run at around 90hz compared to a standard 60hz monitor.

I'd narrow it down to these;

NVIDIA™ GeForce RTX 2080 Ti | 2080 Super | 2080 | 2070 Super | 2070 | 2060 Super | 2060
NVIDIA™ GeForce GTX 1080Ti | 1080 | 1070 | 1070Ti | 1060
NVIDIA™ GeForce GTX 980Ti | 980

AMD Radeon™ RX 5700 XT | 5700
AMD Radeon™ RX Vega 64 | Vega 56
AMD Radeon™ RX 590 | 580 | 570

Look for models with 8GB of VRAM.

You can pretty safely cross off the very-high end too - the 2080 Ti is an $1100 card new, the 2080/2080-Super are both pretty damn pricey too. You're not likely to find any of those used for a sane price.

So then just look for the best price on a used one among the remaining models.

I just bought a GTX 970 for under $100 shipped.

The 1070 is definitely better but will cost closer to $200 used.

Anything better will probably go up from there.

I was figuring between $100 to $200 for a used GPU so that's good to hear.

As far as the rest of the system they recommend: Intel® Core™ i5-4590 or AMD FX™ 8350, equivalent or better and minimum of 8GB of RAM.

This will be a dedicated computer for the VIVE so it does not need much else. Any idea where to pick up a bargain used computer that meets these specs? I see the i5-4590 processor was launched in 2014 so I imagine I can get a system nearing 5 years old.  I'm finding it easy to locate the GPU's, not as easy to determine what I need for the rest of the box. Obviously adding RAM is cheap so not worried about that.

EBay has a buy it now of the MSI NVIDIA GeForce GTX 980 Ti 6GB GDDR5 Graphics Card for $156 shipped so it looks like he can get a reasonable card (it's 6GB not 8, but I found it by looking on EBay for 10 seconds, so the deals are out there). He is not into the grafix intensive games so he should be good for a while.

Obviously adding RAM is cheap so not worried about that.

Used computers are tricky. The 'custom built' systems are often overpriced and you don't know who built them or how well they work. Mainline computers (ie Dell, HPs) are often terrible for gaming due to expandability issues and crap PSUs so that's tough unless you get one of their gaming editions.. but given those cost crazy money new they tend to be too expensive on the secondary market as the owners want to recoup too much of their investment.

The big question is whats your budget? If its $500 or so I'd just build something using used parts where necessary (ie the GPU). If you keep an eye out you can usually score a Ryzen 5 CPU with a Motherboard for $200. The rest of the compnents would be pretty cheap to get.

Also every Wednesday EVGA has 'mid-week madness' where they sell a bunch of refurbished stuff for cheap. I've bought PSUs from there and they are in good shape and come with a warranty. They usually have a wide array of video cards as well. It's only active on Wednesday though:

As far as the video card, look at the 1070s before you pay $156 for a 980, going by ebay solds they can go as low at $160s-170s and they would be a reasonable step up from the 980. I just went for the 970 because I'm cheap and it runs the stupid card and strategy games I play just fine.

My EVGA 1070ti overclocked to 1080 speeds runs everything I can throw at it at 80+ FPS on a 1440p 144hz main monitor with 2 1080p side monitors on and running discord, chat and about 20 open browser tabs  ;)

Ryzen 3 3200g + Mainboard for $135, hard to beat that

So using this as a reasonable starting point I can price things to see what building a computer cost if I want to do one from scratch.

I'm assuming the BOM would just be this?

CPU/Mother board - $135
GPU (used) ~$150
RAM 8 GB minimum - $?
Hard drive - $?
Case - $?
Power supply - $?
Operating system - $?

Am I missing anything? Case fans? Hardware? Cables? Heat sink paste? I don't know what is generally included when you buy a case, CPU, etc. Just never built a computer before  :P

CPU/Mother board - $135
GPU (used) ~$150
RAM 8 GB minimum -  PC4-19200 288-pin DDR4 - $20 for 8GB, cheaper as you go up, i'd drop at least 32GB into that setup
Hard drive -  varies, free to $300 for high capacity SSD.
Case -  guesstimate, $75.00
Power supply -  free to $75.00
Operating system -  free.

Sata/Misc cables - free? just ask here. :)
AS5 - $5.00 a tube. for your paste.
Fans - free to $80, depends on how quiet, how many. motherboard/CPU should come with processor fan. case may come with fans.
DVD burner - free. if you want an optical drive.


not in stone, but i think rough values of parts you asked about.

I would go with this bundle... its 3x the CPU , and only 2x the cost.

https://www.newegg.com/Product/ComboDealDetails?ItemList=Combo.3930018&Description=amd%20ryzen%205%203600


it's actually 3 times as good at 3 times the cost, too. six's deal is $124.95 right now vs $385.99...hey, i understand the budget build. :)

i'm typing this on a mega-fast i3 HP touchscreen with...well, i see a picture, so the graphics card is perfection. :P

Jack's MB will support newer processors, i just have had bad luck with ASRock boards, i have had better luck using Asus boards.

But you could do the ASROCK , i would still stick with a Ryzen 5 or better, a Ryzen 3 is like a Core 2 Quad from 2005...

My I7-4790K is technically faster then the Ryzen 3 posted, and i also have a GTX 1080... Games on an M2 Sata.. and 32gb of ram, and it STRUGGLES to play many of the newer games badly ( like Player Unknown Battlegrounds and ROE )
