Yeah, aforementioned reasoning is why I plan to run Dreamcast (Blitz, Gauntlet Legends) and other consoles.
I think Intel may be an option, but I'm not up to date with the latest CPU offerings myself. I'd ideally like to see a rig in the 300 dollar range that's just mobo, cpu, ram, and hdd (unless video cards actually matter for this, then bump it up to 350-400).
I'd be looking to order 4 of these setups, so I'd be curious as to the best bang for the buck.
