It really looks like it only supports pentium 4....my suggestion....look for a secondhand combo deal, someone who is upgrading and getting rid of the 775 cpu and mobo. Look what you can pick up. Maybe you'll find a nice mobo with quad cpu for cheap.
thanks for the everything. do you have any idea for graphics card?i ask because the radeon hd 5570 i had ordered it doesn't exist anymore and so i ordered a palit gt 430 with 1 gb and i would like your opinion on that because it is pci express 2.0 x16 and the mobo has pci e x16. the previous card was 7600 gt 256mb
