Hello,
I have an I-5, on an asrock z68 extreme3 gen3, 700w power supply. Would using a geforce 9400 gt video card do anything for me, or is it too old to be worth using?
The 9400 GT is a very low-end card. You won't get that much of a performance boost. There are alternatives that use equal or lesser power and still deliver better performance. So, I suggest you get a new card.
Thanks everyone, I just had it sitting around, and i tried putting it in and it ran for a short while, but then crashed while playing planetside 2 beta...doesn't crash when I use integrated graphics. Well, time to start saving
