Will these video cards fit in my motherboard?

So a year and a half ago I bought a new PC, a Dell XPS/Dimension 420. Yesterday, my video card died, so here I am!

All the new video cards require a stronger PSU than my current one (I only have a 425W psu), so yes I know I'll have to upgrade.

Anyway, I was thinking of getting either the ATI radeon 4850 or the 4890, but I am not sure if it will fit in my motherboard properly. Here are some pictures (not the best quality) I took of the insides of my computer:

A friend of mine said that my motherboard is backwards, so getting a PCI 2.0 card wouldn't fit properly because of the black box would be in the way (no idea what it does, I think it funnels air to the cpu?).

What do you guys think? I was thinking of getting either:

Radeon HD 4850

or Radeon HD 4890

Any thought? Thanks!

 

You may well be limited to a single height card in that space. I would recommend a nVIDIA 8800GT: http://www.inno3d.com/products/graphic_card/gf8/8800gt.htm

 

That's actually the card I've been using for a year and a half. I would LIKE to get a newer card, but it seems like all the new cards have larger height dimensions.

If I purchase a video card and it doesn't fit, I can always return it to the store I bought it from for no additional charge, right?

Thanks for the reply!

 

Possibly. Many stores have a restocking fee, and some have an "exchange only" policy, meaning you can return it, but no money back, they will replace it with another item of the same cost. If it's more money, you pay the difference; if it's less, you have a credit, no money back. Be sure to ask about the return policy BEFORE buying a new card. What you need is a "single slot" card. This means that the entire card with the cooler takes up only one slot. Many (most) newer cards use two slots due to the size of the coolers. However, many NVidia 9600GT cards are single slot, as are some NVidia GTS250 cards. Do some research before jumping into a purchase. And be 100% sure that it's the video card that has failed, and not something else. Good luck! Let us know what happens!
:-D

 

Just for your information a 9800gt is 9 inches long. The newer nvidia cards are about 10.5 inches long.
