system requirements help

haven't gamed on a PC in probably 20 years so i'm very out of touch with current standards and could use some help.

getting a Quest 3 as a gift soon and wanted to figure out if i can get alyx going on my workstation/server by adding a decent GPU to it.

i have a couple of HP Z640 systems being used as servers which I'm thinking of repurposing one temporarily for this game.

  • E5-2637 v4 (quad-core, supports HT)
  • 48GB RAM
  • option to use SATA3 SSD or PCIe NVME for storage
  • true PCIe3 x16 slot - can have up to 225W for GPU
  • 925W PSU

minimum alyx requirements per steam is an i5-7500 which is a generation newer than mine so i'm mostly concerned about this and how much of a bottleneck it might be.

gtx 1060 is the minimum GPU requirement and i don't mind getting a 1080 or better but unsure if a much newer gen GPU would make a difference as the xeon probably won't keep up with it anyway.

i am also constrained by how much power i can feed the GPU as the system has dual 6-pin connectors which i'm going to combine to a single 8-pin connector using an adapter, so i can't get anything fancy like Ti cards which need dual 8-pin connectors.

can this configuration run alyx, and will i get to at least Medium gfx performance in the game?

thx in advance.
