JW-790GXT-FUSION its your best bet ... I hope ...... But why dont you exchange your DDr2 rams to DDr3 because There are lot off good pure drr3 board out there..or buy a pure ddr2 board because there are not much difference in performance betwen ddr2 and 3 and you can use your 6 gb ddr2. Fusion board like this is not that good because you can only use two socket of ram.
think i might just go for an am2+ motherboard keep my ram and buy new graphics and processor
with the am2+ slot is there anyreason for this to be worse than an am3 if im only using ddr2? and is it worth me getting a slightly slower processor if the motherboard wont make the most of the processor?
