I'm considering buying a desktop for post processing with PixInsight. In a thread on laptops for post processing some of y'all were saying a gaming laptop with 16gb of ram a SSD - blah blah blah would be appropriate A couple units linked were 12-1300 bucks. This can all be had for a lot less when doing a desktop right?

 

So what specs would you look for in a desktop if you had 5 or 600 to spend?

I strongly recommend that you save up more money.......

 

I run PI on a Lenovo E440 (Intel Core i7 - 4 Cores / 8 Threads) that has been upgraded with a 1TByte SSD, an additional 256MByte M.2 drive and 16GBytes of memory.  Its performance is acceptable.

I agree with Jim, save your money if you want great performance. I spent roughly $1K on an AMD Ryzen 7 2700X CPU, MB, and 2 M2 SSDs. The performance is great, no I just need hurricane Dorian to go away so I can collect and process!

One additional note - Specific functions such as DrizzleIntegration suck the life out of the above laptop....

Well, I just finished the 45 day free trial of PI on my budget laptop. 4gb RAM, Intel i3, 2.40 GHz So from what I have been seeing, it looks like a lower end gaming system at around 700-1000 will be a far cry from what I have been using.

If you want more bang for your buck then I would build your own desktop, you can find some awesome deals on good used parts. If that's not something you are interested in then I'd save up a bit more and buy one of laptops recommended to you, if you don't need the portability then just go for a premade desktop.

So I found a used desktop system with these specs.

 

16 gb ram
AMD FX™ - 6200 Six-core processor 3.80 ghz
Radeon ™ RX 480 graphics
asus m5a97 r2.0
1T HHD

 

Opinions?

The HHD is the weakest link in that setup.  Get an SSD instead.  Old school hard drive with moving parts are good for storing data but not for the operating system and certainly not for PI's cache files.

 

Otherwise, looks like this would be a decent upgrade from your current low-end laptop.

How much are you paying for that? That CPU is really really bad. If you do end up getting that system, then like guyroch said upgrade to an SSD asap.
