Why would anyone buy the 5830?

Currently, I'm trying to figure out why anyone with a modern Xfire board would buy a 5830 over 2 of thses:


2 of those beats the 5870, and at 250$. The 5830 no longer has the 250$ zone locked up.

Or you could buy this for 250$.


So if i offered you a Xfire compatible Motherboard, and you're choice of he 2 card setups, what do you chose?

    Adding even more value to the Radeon HD 5830 is its overclocking ability, though this is still a bit of a gray area right now. Although we were able to reach a core clock of 900MHz and a memory clock of 1300MHz, it appears that AMD is limiting overclocking performance at the BIOS. Already this small overclock provided us with performance gains as high as 17%, but imagine if the core could reach 1GHz.

    At this stage it is not clear why AMD is limiting the overclocking performance of their graphics cards. Perhaps they are trying to avoid the throttling issue that we found when testing early samples of the Radeon HD 5970, though this is not an issue we have found troubling their single GPU solutions. Honestly, we have no idea why AMD are doing this, as it makes very little sense to shutout the enthusiasts.
  2. 5830 OC loses to 4890 OC.
  3. Charts plox.
  4. The 125 5770 your using in this argument, (really 135 sans rebate) does not have eyefinity available also with its 512 memory would run in to trouble over 1920x, but yes it would be powerful. If the prices fall like this
    5770 165
    5830 240
    5850 310

    The 5830 makes perfect sense to me.

  5. The 5770 1gb is 150$. The 512Mb is 125$, and when you use then in xfire, you end up with 1gb of memory.

    So, Orignal Quastion: If i offered 2 of the 5770 i linked and a xfire mobo to you for free, or the 5830 and the same mobo for free, whta do you take?

    not how it works at all, you don't add the mem together since one card can't reference the memory from another

    also look at it this way, if you use AFR (alternate frame rendering) each card has to have a copy of the scene in memory (albeit at game times) so each one would need its own memory to render the scene

    spend the extra $25 ($50 for 2) and get the 1GB models

    keep in mind 512MB might be enough for now (1680x1050 and lower), but games use more memory overtime and having 5870 speed with 512MB per GPU could cause it to render a lot slower in the future
