looking at the GIGABYTE MA790FX-DS5 mobo...

looking at either the 5000 or 6400 BE for a processor to use with this mobo.
what do u think about this combo?


can i use ddr2-1066 with these cpu's? or does it downgrade it to 800?
i was looking at the corsair dominator ddr2-1066 (its on sale at newegg)
possibly maybe 4 sticks, but im only running winxp


other specs i wanna use with this system:

coolermaster 690
corsair 520 psu
evga g92 8800gts
150g raptor

i wanna start with solid chassis by getting an am2+ mobo so it will give me more options to upgrade in the future.
