And the AV8 3rd eye is the worst board for overclocking, I can't raise my FSB 1mhz with PCI lock on, and have the ability to play games.
DFI lanparty, 6600gt and a 3200 venice is a lovely combination. Or if you are not desperate for a pc now, the new GPU's are worth a look at if they are not too pricey, but even if they are, the 6800gt would be alot cheaper.
edit: I would wait anyway, if you can afford it get one of the new series from either ATI or nvidia, or get a 6800gt.
