what affect does that have on performance?

thats truely bonkers im shaw that the Manufacturers think we have bottemless pitts of money now.

These are rather good value if you think about it.
Take the rampage 3 extreme for example. It's near on £300. Add an Bigfoot network card for £70. Then throw in an £80 x-fi... It's now at £450... Yes the boards are still more money but there are other features such as an nf200 chip which is far from cheap. The main gain in having all of this integrated is that you have 2 top products that now don't use up any valuable expansion slots which means ramming 4x 580s on to the board is now not only possible but you don't need an UD9, or classi 4 way to do so which means normal cases people! No stupidly over priced cases adding to the system cost.
Factor in everything above and it's clear that these although expensive are exceptionally well thought out and very good value for money![]()

I beg to differ. £450 for a mobo is about £350 too expensive for me.
