We are planning to get many more servers up, the back end is just taking us a bit longer than expected. We're having a few problems with our new boxes performance wise allowing them to handle the amount of players we want. The first new one went fine with the overclock and didn't overheat at all, but it seems on the second box they used a much cheaper heatsink.
I'm sure some of you know that SRCDS is heavily single threaded and doesn't do too well with multi-core CPU's, so it greatly benefits from high clocked CPU's. Which we need to run servers at 40 slots or higher, like Office and Dust2.
