Best cheap gaming rig that's good
It's been discussed but I'd like to give my 2 cents. I just purchased my second Dell T5810. This one is for my boy to replace a dated optiplex. I considered building from the ground up. Anything decent is stupid money for me. I bought the 5810 from eBay. 200 bucks free shipping. Came with the 685w psu, e5-1650v3 cpu and 16gb ram. 4z4gb ecc 2133 memory to be exact so it's running quad channel. As most of you will have some stuff to carry over like me that's one hell of a value. I re used his 250gb Sata SSD boot drive and here is something new I found by accident. I took it out from his optiplex and stuck it in. The 5810 booted right into windows no problem and activated it. The 5810 did not have a license. Now it does. I then did a clean install of windows after that. Other than that I'll be adding a striped storage space pool from the old PC that contains his games. I also bought a gtx 1070. At the time writing this that's the best value GPU on the market right now. Going for around 300 bucks and has equal performance to a 1660 super or an rtx 3050. Both of those cards are going for much much more. So all in I have about 540 bucks into a full gaming PC. He's on a 1080p monitor so it should play just about everything at max settings. Obviously as times settle down the GPU can be upgraded and the max cpu that can go in this is an i7-6950x. Those can be had for about 250 bucks on eBay. 10 cores with decent speed. That would make this machine comparable with a i9 9th gen cpu.
So for anyone reading this wanting to get into a good PC for cheap I'd go after one of these. I'd advise against going older and any newer just isn't cost effective yet. I've done alot of things to my t5810 that I use not for gaming that I didn't discuss here. It's not relevant to being cheap but there is alot of headroom with these if your willing to tinker.
