Blade_Runner's config was absolutely perfect! A Powersafe is the least PSU I would recommend below an Antec. The Colorsit isnt all too good.
IMO, it aint worth going for the 3200+ over the 3000+ for a mere 200Mhz speed gain , the 3200+ is almost 2000 bucks more than the 3000+ ! However i believe price cuts are expected from AMD, and the 3200+ could become as cheap as a 3000+ proc.
If you're looking for a motherboard with onboard graphics, the only option is the MSI RS480-M2 . The other option would be Geforce 6100 based nvidia boards, unfortunately I havent seen them in India yet.
If you want to forego onboard graphics, you would need a PCI-E board + Geforce 6200TC. The Cheapest PCI-E board i've heard is the Winfast nForce4 Ultra, sells for around ~ 5k. A 6200TC would be around 2.5K, which ends up around 7.5K, so considering that it could be a *bit* expensive, but on the whole would be better.
The MSI board is a pretty no-frills board, no PCI-E 1x slots apart from the PCI-E 16x slot, mATX form factor, and NO overclocking !
This answers your above question - 3000+ and 3200+ processors can be overclocked, but that entirely depends on whether your mother supports overclocking !
