Quick note: I haven't actually run any upgrade wizards in a while. I'll do that. Restore point first and then get Steam to do it for me.
I've noted that game has been started to use 100% of CPU resources around the time i20 hit. Before that I had some breathing room in terms of processing power. But as SP1 hit at the same time, I blamed that.
The motherboard won't support any more RAM.
But considering the deal I got on the system at the time, I can't really complain.
The power supply should support everything in the system. I've upgraded it myself from the tiny 320W to a decent 750W.
The switch is a network switch/router. Its supposedly the step above a router but works the same way. We've transferred MASSIVE files over the LAN rather quick but hook up to the net and any computer is 50kB/s. This is regardless of the number of computers on.
Normally I don't have lag or rubber-banding...which is rather nice. Just this Incarnate system is frustration. Normally when I'm playing CoX I don't do silly things like try download 90MB trailers in the background.
----edit---
Steam is updating AMD graphics driver now. For some reason I couldn't create a restore point. It kept "timing out". There's only one hassle of using Steam... All those things I want to get... Orange Box, Portal 2 (waiting for it to come down in price) TF2, Civilization, ... and much more.
Anyway, here is what Steam says is my System Specs are, before the update.
