Quick PCIe question

So this is my desktop: http://www.dell.com/us/p/inspiron-570/pd
And it says that it has these slots; PCIe x16(1), PCIe x 1(1), PCI(2)

Even though they are PCIe 2.0 or 2.1, can I use any of these cards in the PCIe x16 slot?

More about quick pcie question
  1. I have the Athlon II X4 processor so bottlenecking won't really be a problem

    So if all these cards require two slots, will they not be compatible with my motherboard?
  2. Oh those. I have an integrated HD 4200 on there right now, so all the 4 "slots" are open. There's no dedicated graphics card installed in the computer at all.

    The motherboard looks kind of like this;

    The 4 slots for the DVI/HDMI ports are all open

    So if I upgrade the PSU to something around 600w, I'll be able to install this card, no problem right?
  3. ..lol nice analogy. but yeah, i get you. i was skeptical of that PSU as well which is why I asked. So would I be able to buy both a 6850 and the xigmatek under $200?
  4. yup, looks good! also, what company do you recommend for the graphics card? HIS? Sapphire? ASUS? Which one?
  5. lol good advice but shouldn't i be looking out for warranties and such?

    or are they all good enough that it doesnt matter?
  6. oh and what about Powercolor?
  7. I guess I'll be upgrading in about 2 years again..but I might want to sell it then so I don't really know lol
  8. Oh one last question!
    Will I be able to use a PCIe x16 2.1 graphics card on this motherboard?
  9. but this motherboard only has a regular pcie x16 slot
  10. Oh ok then, got it.
    Thanks again! I have a question about multiple monitors but I'll be making a new topic for that
