I've been using my old 2013 ASUS laptop for Photoshop and running my telescope/camera/cooled CCD for a few years but it could no longer keep up so I built this. It benchmarks pretty well against other systems in the PixInsight database considering I'm running a stock cooler. If the CPU starts to require more cooling as it ages and gets dusty I will probably upgrade to an AIO. For now it consistently scores just under 10000 in all three benchmarks and chews up data with a swap speed of 1900MiB/s. Installing proper swap directories and using 4GB of memory as a RAM drive was the key, along with normal overclocking technique on the CPU/RAM. Haven't messed with the GPU yet since I don't do much gaming anymore.
CPU OC to 3.8GHz @ 1.325v, RAM at 3200MHz 1.2v IIRC. May upgrade to 32Gb of 3200MHz eventually.
