ok so my friend is trying to upgrade his old 4350 radeon 512 mb on-board of DDR2 card to a radeon 6350 1gb of DDR3 card. I wasnt really sure myself, frist time I ran into this problem and I've put together 2 computers. The RAM on his motherboard is 2X2 sticks (4gbs) of DDR2. So my question is could that card be put in without problems with the difference of DDR2 card to DDR3 card? I also told him he should probably get a bigger power supply (using a 350watt, recommened a 500watt) Thank you for your time.
