sry 1 more question as seen above i have RADEON X300 Series video card and id like to up it...i was thinking Radeon x700 or if i get enough $ x850 are these good choices for gaming or re their better ones around the same price?(i should prolly jus start another thread)
i have an x300se. how much gaming are you wanting to do? my x300 can handle doom3 at 600x800 at medium settings @ 40-60 fps. unless you are and uber-games-master, x300 will be fine.
be careful upgrading, as with dell, you cannot just upgrade ur psu, which you may need to do with a more powerful gfx card. dell use propriatry psu's, and you will have to get a more powerful one from dell. what is the wattage of your current psu?
if you open ur case it should say on a sticker on the side, or, as it is a dell, look in the product information guide that came with ur comp, and look in the technical specifications section in the back. it will say under the psu section.
