I guess what I'm trying to do is find out about tech, that I'm hearing about.
My last computer build was ~8-10 yrs ago, and it was just a GP machine - as such it's been little effort to keep it running and it's not been stressed as far as effort is concerned - replace a couple of power supplies, updated the OS, that is all it's needed.
Most of my gaming in the last ~7 yrs, has been on a console, mostly due to a couple of specific games ( think LAN parties of 5-8 people at a buddy's house) so I have not been paying much attention to the computer building side of things. Now I tried ED on console and I like it, but find it a bit more limiting than I like, so I'm looking into building an entertainment PC, that will replace the console.
The concept of SLI ( or at least from what I'm understanding it to be ), is something I was wondering about ~10-15 yrs ago, but to be honest, since this is the first computer build I'm doing in ~8-10 yrs, I'm not totally sure what it is, and how it works, or where I might start. Does my previous post, now make more sense?
