I like my p4 setup, but the asus nforce 2 board is probably the best mobo on the market right now. If you're looking for specific features on your next mobo, then for price/performance, it's hard to beat the a7n8x. The new granite bay boards are too scarce and way too expensive. I'm still waiting for sis 655. I hope sis responds to my email soon. I'd go for the 512 meg winbond case 2 pc3200. Hardcore cooling has some for $149. If you stick with the p4 setup, go for the asus p4pe or albatron px845 pev pro II.
