How many people do you plan to host? If it’s more than 5, I would suggest getting a better processor. If you have ~$45 laying around get a Intel Q9650. I used to have a old 775 system and I had gotten a bargain deal for a nice nforce 790i chipset mobo and q6600 for $75. I got a q9650 and it was a lot better for hosting compared to the q6600. I flipped that for a profit since I included two 660s with sli bridge and got what I have now.
And if you want to see how it feels, feel free to join the server as I’m just having it run and I’ll keep it running for a few days. ovingiv.ddns.net:25565 <=== That’s the address to use.
