There are many solutions to the current graphics card crisis. One is to just bite the bullet and pay the inflated prices—desperate times and all that. A better option is to buy a pre-built machine, which tends to have better value since PC makers buy components in bulk.
Amazon has a great deal today on a certified refurbished HP Omen gaming rig via Woot. For $600 you get an HP Omen 870 desktop PC with a 3GHz, quad-core Intel “Kaby Lake” Core i5-7400. (Note there’s a misprint on the Amazon page saying the CPU is an i5-7700, which doesn’t exist.) A 3GB Nvidia GeForce GTX 1060 handles graphics and gaming duties, paired with 8GB of RAM and a 1TB hard drive. This deal ends just before midnight Pacific Time on Monday, and it’s $300 off the listed price for the system.
