I just upgraded from an Athlon64 3200+ 2.0GHz processor to a dual core Althlon X2 4400+ 2.2GHz/core and it totally owns! Not only can I watch TV with my TV tuner card on my second monitor while I play but also, it seems like one of the processes involved with people running around town can be split off into the other core so now I can zoom around town without lagging at all even at full detail. The fact that I had a Geforce BFG6600GT graphics card was what I thought was holding it back but apparently it's a processing thing. On a side note, I tried to get the CPU to 100% and while encoding a video at 2 megabits in WMM and playing a song in WMP and watching TV on my other monitor it was at a constant 86% so they're pretty amazing. I heard some games like WoW crash on a dual core unless U disable one core but SRO apparently doesn't so get one if you can
