@ Bullzi,
Well let me clarify some things, which should make things easy for you
1] X48 is nothing but cherry picked X38, both of them have absolutely no difference.
2] Looks like future is all X48 BUT most of the X48 board will be on DDR3 platform so no problem going with X38 with DDR2 as of now.
3] You should look at Abit IX38 QUadGT, very nice board,superbly priced and clocks exceptionally well. 582 FSB anyone ?
4] Asus Maximus Formula is a good board but really targetted at extreme overclockers, are you going to do that ? If not then why waste money ?
5] 3870X2 is a very nice card, you can surely go ahead with it.It has good VFM. Keep in mind that you wont be able to overclock it much as it runs quite hot.
Btw, since you will be buying a new Mobo, you wont be needing your P5B Dlx right ?
Would you be interested in selling it
I would like to pick up one
I know i am shameless
