6850 or 6870

Should I save 30 bucks and get a 6850? or Just go for 6870, what's the performance difference? I'm planning to upgrade to like a 7970 next next year or something.

  1. Around 5% framerate, on average, according to this review:
    http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/37499-hd-6870-hd-6850-vs-gtx-460-1gb-overclocking-study-15.html
    That's 3 fps in the neighborhood of 60.
  2. So should I cut down on the graphics card to get a 6850 and upgrade my mobo?
  3. All your specs, please. If a 7970's gonna be as good as its model number suggests, I hope you've got a 2500K or similar. The mobo will depend on everything you've got ATM.
  4. Specs, PSU, CPU, Motherboard, RAM, HDD, SSD, Case, etc. If the hd7970 is anything like a hd5970 was when it came out, it should be a great card. I heard that the hd6870 was 20% better. Here, take a look at this. http://www.anandtech.com/bench/Product/291?vs=290
  5. At full HD, it seems the 6870 is only up a few fps.
  6. I would not get a 7970 with that set up. RAM, CPU, HDD, Case are all good, but the motherboard isn't too great. I would save the money on the video card and grab a better motherboard. That CPU is not for a high end GPU like a 7970.
  7. Yeah I want to get an AM3+ mobo so I can upgrade to bulldozer. So should I get a better mobo (and a better CPU later) and upgradee to 7970 in 2 years or so?
  8. The CPU is certainly not enough for a new flagship card. In fact, flagship cards in general aren't worth getting. They're usually hot, loud and very expensive. You'd do better with Xfired lower-end 7000 cards or 6970s. Don't fixate on the single "fastest card".
  9. My PSU will only be enough for a single card though.
  10. Best answer
    550 watts will certainly not be able to handle a flagship GPU. Decide now: I'd go either single 580 or multiple-card, if you're thinking on the level of a 7970. You'll need a 2500K, though.
    What kind of budget are you working with? I've kinda been assuming you're going high-end, since you picked a card so high-end it's not even out yet.
  11. PSU:
    You must look at both Wattage and Amps. All graphics cards list the Amp requirement (specifically on the +12V rail). For example, I've seen 500W PSU's with only 20Amps and ones with almost 50Amps.

    A GTX570 requires roughly 38Amps so I usually recommend 48Amps such as the Antec 620W High Power. The next-gen of graphics cards will use roughly HALF the power so that means you can get more processing power but keep the same PSU.

    Other:
    - Intel CPU's (was an AMD fan for years) unless the charts show better value on an AMD versus Intel for the price, go with Intel. Look. At. The. Price. Vs. Performance.

    - the graphics card is usually the bottleneck in a gaming system. I still recommend spending roughly $200 on a CPU for future upgradability of graphics if needed or other tasks like backing up your system and converting video.

    - I've found my HD5870 can handle most games at, or near 100% quality at 1920x1080. I discovered, however, that going much below this card can quickly drop the frame rate or quality. You can spend $1000 on your system, but there's a HUGE difference between a $150 and $200 graphics card of same quality.

    - PhysX is still a non-issue for me at the GTX560Ti level except for a few games like Batman AA that can play fully quality at 60FPS 1920x1080 and also keep PhysX on full. If it's a choice between PhysX and Quality/FPS I'll choose Quality. I don't want PhysX to drop my system to 40FPS and also get screen tearing when I can lock to 60FPS fully quality.

    Summary:
    - GTX560Ti or HD6950 is what I recommend
    - AMP requirement for graphics cards. Understand this.
    - bottlenecks determine best value.
    - recommend Intel i5-760 or similar
    - Tomshardware has great articles on building
    - NCIX, Newegg etc.
    - non-stock HSF for CPU. $30 to $50 (quieter even in idle and great for overclocking)
    - overclocking won't benefit games usually (graphics bottleneck)
  12. 760? You're crazy. The 2500K, for $10 more, will be good for years with some mild OCing when the OP gets a GPU that's good enough to need it.
