Pci-e 2.0x16 vs 2.1x16

I was looking through motherboards and I was wondering what is the difference between pci-e 2.0x16 vs 2.1x16. From what I checked, 2.1x16 supports some management/troubleshooting stuff etc, but is ultimately the same speed as 2.0x16. I guess my main concern is, does 2.1x16 work with 2.0x16 slots? I'm assuming yes, but I don't want to assume and be wrong lol because I was thinking of getting this http://www.newegg.com/Product/Product.aspx?Item=N82E16814150492

More about 0x16 1x16
  1. PCI-E 2.1 cards will work perfectly fine in a PCI-E 2.0 slot
  2. Their is better card if you were intrested about 5 bucks more the next model up...The Radeon HD 5570 is the same power requirment a lil bit faster and has DDR3.

    I'm not sure on this myself but i had the same question...From my understanding they are both compatable and will work 2.1/2.0 with eachother, but the 2.1 is a little faster ...i don't know if that would hamper the cards ability to perform better it being a 2.1 card and putting it in a 2.0 PCI-Express slot but it will definitly work.
  3. I agree with Maziar . its what i have seen before .

    well, I'm definitely interested in better cards, lol. I kind of was considering this one because of the price. It's 69.99 with a 15 dollar rebate + free shipping. I guess on newegg there is also a 10% off all graphics cards right now, so that is why I'm kinda on newegg right now. That would make it all together 68.19 (cuz of tax) without rebate, and 53.19 with rebate. So that's kind of where I'm standing right now, between price & quality lol.

    If there is a better deal, most definitely let me know, lol. thanks
  5. i wouldnt get a HD5550 ddr2 when a HD5570 ddr3 is the same price. same rebate but you have to pay for shipping.

    id rather go for the sapphire then powercolor though in terms of manufacturer.

    but then again why go for the sapphire HD5570 when the sapphire HD5670 is the same price with the same rebate but you have to pay for shipping.

  6. Well i could suggest the Radeon 5570 i have it and it treats me good. I can play all the source games like Team Fortress2,Counter Strike Source and plays Modern Warfare 2 almost maxed out around 40-50fps. I think your looking for a cheap upgrade so ur budget is gonna be low? I was also wondering if you know what type of PSU(Power Supply Unit) you have?

    But what i found was the same deal just no rebate, but free shipping.The 5570 is better than the 5550. Better Memmory(DDR3) and the clocks are a little bit faster.
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814131342&cm_re=radeon_5570-_-14-131-342-_-Product

    I mean what are you gonna do with the graphics card it would be alot more helpful and if you could go 30 to 40 dollars more you would get more bang for your buck if you can spare it.I'm not to sure on Nvidi's side at this price range but the 5570 is what i would suggest cause i run it and i know from experince how it performs.
  7. I would definitly get this looks like a really good deal it almost doubles the 5550 and the 5570 if you have the money i would suggest you take a look at this.

    Their could be even better deals out there keep checking this is the best i could find at newegg

    Oh, I'm not sure exactly what psu I'm using now. It's like an antec smart power 450 w psu as I quickly glance at it, but I was planning on getting a new psu anyways, cuz I'm actually building a new computer. As for a graphics card I am trying to build base on a low budget as I buying part by part. I think I will mostly just be watching movies etc, as I actually don't game too much nowadays, but I actually want to build it to play like scII or modern warfare 2 from time to time.
  9. Well i play SC2 and the 5570 runs that almost perfectly almost everything on high settings/you can play it on max but when you play custom games unit lag will cause it to drop.If it's in your budget than you should get the 5670
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814161334&cm_re=radeon_hd_5670-_-14-161-334-_-Product&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-RSSDailyDeals-_-na-_-na&AID=10521304&PID=3463938&SID=

    since your planning on getting a new computer later on look into getting a crossfire capable mobo then in a year or 2 if you need to you can get another 5670 for cheaper. The DX11 might be better on the 5670 seems like it can handle it better than the others.

    yeah, it's kind of above my budget, i mean i could get it but I don't want to spend that much. So I'm actually looking to get one of these two. Both of these are pretty much the same card, except one costs like 1 dollar more because of shipping, but it has eyefinity that supposedly allow multiple screens sharing the same thing. I don't have multiple screens, but it's like only a dollar more so I guess I'm considering it, but then again, it's kind of unnecessary, but then again it's $1 lol

  11. eyefinity is pretty cool. i never tryed it myself but i'm sure it would look great, anyhow you started out with 5550 went to 5570 now to the 5670 amazing.and pretty close to the same price yet near double the power.Like i said earlier i haven't checked on the nvidia graphics cards maybe you would find a better deal with an nvidia card instead of ati.
  12. http://www.newegg.com/Product/Product.aspx?Item=N82E16814261060


    this one is a bit slower not sure if it has eyefinity but still has DDR5 memory about but its 10 bucks cheaper with free shipping.

    well, I didn't really care about eyefinity anyways, lol. and I guess it is a plus that it's cheaper with free shipping. and i guess I kind of like how it's a rebate check instead of a rebate card lol.

    well, I think I would go with this one, but uhh just wanted to know, how much slower do you think it is?
  14. actually, I think I'll just stick with the 5670 with eyefinity - http://www.newegg.com/Product/Product.aspx?Item=N82E16814102870&cm_re=sapphire_radeon_hd_5670-_-14-102-870-_-Product&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-RSSDailyDeals-_-na-_-na&AID=10521304&PID=3463938&SID=
    since I was about to get it anyways, and I guess the look kind of attracts me more than the palit gt 240 lol

    thanks for helping me out =D
  15. no problem i would go with the 5670 too it's much better and it's alot newr that the gt 240.

    lol, I actually ended up getting this graphics card instead
    XFX GeForce GT 240 1GB 128-bit DDR5 card http://www.newegg.com/Product/Product.aspx?Item=N82E16814150472

    that had a combo with this power supply
    XFX P1-650X-CAH9 650W ATX12V v2.2
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817207007

    as the deal just happened to pop up, I thought it was worth canceling the other order cuz of the price
    for 175.98 + 2.99 (shipping) - 40 (combo discount) - 8.60 (10% off promo code) - 40 (rebate) - 30 (rebate)

    so a total of $140.88 before rebate, and $70.88 after rebate
  17. Wow thats a great deal...it's a good idea to really check everything out and get detail on all the products before making a purchase.Thats a really good buy but i noticed it doesn't support SLI so in the furture if you were looking to SLI with 2 cards you couldn't use that one you would have to buy x2 different card, that power supply is really good for the bargin you get with it.Still though, a great purchase.Goodluck with that, hope i could help you again sometime.
