First Build

USB 3.0 isn't a really a concern of mine right now. I don't own any devices that support it and don't forsee buying any for quite some time.

Also, I won't be overclocking, so I think the 2500k would be a waste of money. I dunno why I put that in there.

My biggest problem with building this PC is trying to figure out which motherboard to get. I definitely want 6gb/s since I have an SSD with SATA III.
 
if you act quickly enough here's a $10 coupon for the i5-2400: EMCKAHA25 ->$180
switch out the p67 to an H67, or 61 board. they're $30-40 cheaper

that mobo will only use 1066/1333MHz ram and it has 2 sata 6Gb/s ports

cheaper HDD (seagate), a lot of people choose the samsung spinpoint f3 $5 more

that's $80 less than your current build. You can put that towards a gtx 560ti or a HD6950 1gb or an ssd.
