Hello. I don't know a lot about computers so i need a little help.I need a mobo, processor, PSU and case that will work with a 2gb GT 440 graphics card and ddr2 ram (also keep in mind that the prices shouldn't be too over the top).
Brand new machines running DDR2 are like hens teeth these days. The GT440 isn't a very powerful card, it isn't even mid-range, it's more of an for an entertainment system than gaming. Jugdging by this older slower tech you'll be looking at ebay. But I've still got to ask, what do you plan to use it for and what is your budget?
I suggest you try selling your ddr2 so you can switch to ddr3; your selection of boards and cpus will be much better. Look for a combo board/cpu on ebay or in your local craigslist. You can sell you ddr2 there, or maybe find a board/cpu combo that uses ddr2.
