For gaming, just get a dual core now (e8400) and overclock it to 3.6Ghz+. There is no point in having a quad core for gaming untill games come out that actually use them (and no, Crysis does not utilize quad core) and dual cores get higher (over)clocks and thus are better for games at this time. By the time multipe (4+) cores are being used in games (and even then, your CPU will probably not bottleneck you yet) Nehalem will be out and I would buy a nice Nehalem board at that time. 8GB is nice, but only needed if you wan't to disable the pagefile in Windows for faster loadtimes, otherwise it's useless to have over 4GB memory.
About the harddisks, just get a pair of Seagates 7200.11 @ raid0 will be all the speed you need for gaming.
Also, I stand by my point to wait for the new GPU's coming out (nVidia or ATI) and get one of those if they are as good as promised (read; IF), so you can upgrade in the future. The 9800GX2 still doesn't work flawlessly in quad-sli, so an upgrade from 9800GX2 is useless at this moment (and nVidia hasn't been to keen on getting quad-sli to work properly, so who knows when and if it ever will; correct me if I'm wrong here).
