Need Some Help

hi there, i am thinking about buying a AMD 64 3400+ but i am wondering if that can be overclocked to 4000+ with Asus A8V Deluxe w/ DualDDR400, Audio, Gigabit Lan, SATA RAID, 1394 Motherboard. If not this CPU, then which one can be overclocked to 4000+ and what sort of cooling is recommended. I have 2 modules of PC3200 512DDR and ATI Radeon 9800 Pro, with Audigy2 ZX Platinum Pro. What sort of power supply is recommended, every help will be very appreciated as i am not updated with the new 64bit generation.
Thanks

All chips clock differently, read the stickys for o/c results, it seems the best way to go at the moment is vencie or san diego. All depends on your budget. The rest of your system looks ok. A good quality psu would be essential. Antec or fortron seem the best.
