I am in the same boat as the OP. My rig is very similar to his. Same processor a 1gb ati 3870 graphics card. I run 6 EverQuests and my processor is pegged. I can run 5 wow's like a dream. I am running them with ISBoxer and it is manageable for now but I am looking for an upgrade. Do you think i7 Quad Cores would hyperthreading would make that much of a difference over the older Q8600? I was thinking of upgrading my video card to ati 5770 but graphics doesn't seem to be the issue. Maybe more RAM but I have 8gbs. Anyone have any luck boxing 6 on EQ using ISBoxer? I figured my rig would eat up a game that requires a p2 400mhz processor!
