More about 270x crossfire single 280x
  1. Best answer
    Two 270's would cost much much more than one 280, and since power is lost in crossfire, will only perform a tiny bit better than a 280 on its own.
    Besides, when mantle comes out, crossfire will not be needed. The 280x is the better option in his case. A 700w power supply would also only just handle two 270's (with barely any room for adjustment) while it could easily handle a 280. I would go for a 280. Plus, a 280 will be able to handle pretty much all current games on high-ultra, and will be good to use for another 2-3 years, crossfired 270's will pretty much do exactly the same thing, offering a tiny bonus of about 10 extra fps at most. 280 is a great card that can easily meet your needs. No need for two 270's. Not worth it.
  2. Mantle isn't going to suddenly come out for every game, just a few. I just watched a video with Tim Sweeney, John Carmack and I think a guy who works on BF4 discussing this topic.

    I suggest you compare BENCHMARKS for the 280x to a card like the MSI GTX770 as that card is about the same price (it's $330).

    If you compare apples-to-apples the MSI OC'd GTX770 beats the MSI OC'd 280X slightly.

    Other important details:
    a) GTX770 comes with THREE free games ($150 new):
    - Batman Arkham Origins
    - Spliter Cell Blacklist
    - AC4 Black Flag

    b) Shadowplay (can record 1080p @60Hz with little/no game performance loss. I tested this.)
    c) PHYSX
    d) SLI beats Crossfire currently (if you ever add another card)

    e) G-SYNC:
    This technology which is currently NVidia only (may be licensed) works with new G-Sync monitors (Q1 2014) to solve lag, stutter and screen tearing all at the same time.

    *G-Sync is a game changer. It's not a minor thing. The experts are all talking about it and blown away.

    The difference in VRAM (3GB vs 2GB) is still not that important.

    Summary:
    - MSI GTX770 is faster slightly
    - G-Sync (me want new monitor.)
    - three great games!
    - AMD's Mantel isn't going to make much impact in the near future if ever (can provide links)

    Good point but the only problem is I cant order from new egg cause im from the philippines and the prices here is way more than in US...
  4. Sure,
    I'm just trying to give you all the options. Keep in mind the $150 value in the games if that factors in to your decision.

    The GTX770 prices just dropped very recently so it's also possible your stores haven't updated to the new pricing?

    In North America the MSI GTX770 is barely more than a comparable MSI 280X ($330 vs $310). That's $20 difference but $150 in games. If AMD has any games included I couldn't find them mentioned.

    Good luck.

    Oh my god...you truely mean that an advertisement event from nVidia itself says good stuff about a technology from AMD? Than you're more naive than I thought an american could be, or you're just another fanboy.

    Mantle COULD have a big boost of performance, but nobody knows this by now, so time will tell.

    And yes, 2GB of VRam isn't that much. Already in 1080p you can use it nearly completely, without using any texture mods. A good example for this is Crysis 3 or Battlefield 4. Both games use round about 1.6 to 1.8 GB of VRam (in highest settings), so there is nearly no buffer for more in the near future.

    The only real arguments FOR the GTX 770 are the three games, shadowplay and physX. That's it!

    Both are good cards, and yes: It is a really tough decision.

    And sorry for my bad english! :/
  6. oetZzii,
    Try not to throw around words like "fanboy" or "naïve", nor am I even American.

    The video link I provided which you may or may not have watched is very good as the parties actually DISCUSS Mantle so you get a feel for where it might be going.

    Tim Sweeney even expressed interest and asked about the man hours involved etc. I'm personally very interested in it and do give that weight in my recommendation of AMD vs NVIDIA, just not very much. I give more weight to G-Sync, though if someone said "I absolutely won't buy a G-Sync monitor in the next three years" I would factor that in too.

    I also do factor in 2GB vs 3GB.

    We may also see new titles using a Shared Tile resource (or similar name) wherein the main System RAM can store data and send it fast enough to the VRAM for a fairly seamless experience thus reducing the VRAM requirement. That's built into DX11.2 I believe and implemented into the game but it's coming.
  7. My 2 cents, get the best bang for the buck and stick with it for 2 or 3 years.

    If cost efficiency, i would go for crossfire R9 270 (not the 270x). Theoretically that's still better than single 280x and it's not far behind crossfire 270x. Remember a 270 only requires 1 6-pin connector while 270x requires 2. Two r9 270 is approx $400, while a r9 280x is also in $400 range.

    You mind about the future (~3 years)? Ditch your crossfire and do another round of research. I guess not many folks would like to crossfire a 280x in year 2017. There will be newer cards / technologies coming out and these old cards prices don't depreciate that much. Case in point, a good old GTX 580. That's a 3-year old card and who would want to SLI a GTX 580 nowadays? Even if you have thousands of dollars to burn right now, you'd rather spend it on better cards, e.g. gtx 770 SLI, r9 280x crossfire, etc.
