Wanted: AMD Athlon upgrade advice

My old Althlon XP 3200+ and GeForce 680 GT are beginning to struggle a bit - understandable, they're dinosaurs by today's standards. I want to build a new machine, mainly for gaming. But - big but - here's a list of rules: NO SLI/Crossfire and NO serious overclocking. I was thinking an E8400, 2GB DDR 2 - or DDR 3, if there's a reason - 8800GT/GTS 512, Win XP.

I'd like some help choosing the right motherboard/chipset - I have a quiet Nexus case with a quiet 600W 80+ PSU already - memory and anything else I've missed. I have HDDs and optical drives already.

I was going to ask a forum or two, but I figured I'd get drawn into an argument over what overclocks best and why I should choose this brand over that brand, which I don't want.
