$300 Graphics upgrade.

My current rig is an i5-3570K, Hyper 212 Evo, Asus P8Z77-V Lk. I have been thinking about replacing my Gigabyte HD6870, which I do not like very much (looks horrible and I would like more performance). I am thinking of either a 660Ti or a 7950. I would go Nvidia, but i have concerns of futureproofness and its memory bus. As for preferences, the only thing i would buy that isnt predominantly black and/or blue would be DirectCU II or XFX Double D. I occassionaly do F@H.

PS what is the maximum price I can sell my 6870 for?

  1. Decide which games you intend to play, and whether you intend to play any PhysX games (Borderlands 2?) and pick the card that performs best in those games.

    Techpowerup has benchmarks for 18 different games that will prefer one or the other. If you want PhysX, go for the Asus GTX 660 Ti.

  2. Your best bet for $300.00 would be the 7950 and your right on the limited memory bus of the 660 Ti. The only time that somewhat goes away is when you overclock that but at base clocks the 7950 is on top.

    I have this Sapphire(pre BIOS) update for it.

    Solid card. Performs extreamly well at its base clocks. however you can look towards the other Sapphire at $309.99 with the 850/925 clock.

    As for a price for your 6870...I'm unsure. they sell new for ~$150. So an asking price of about $110-$120.
  3. So basically, either way, I will get approximately the same performance right?
    BTW I WILL overclock, so a beefy cooler would probably be needed. This rules out EVGA.

    Toms said that the Asus 660Ti get bad temps on everything that's not the GPU, so I am not sure I would like to go with that.
  4. Yes, under 4xAA. Its when the 660 Ti is pushed beyond 4xAA with out a heavy overclock because of its limited memory bus. Where as the 7950's lose very little(assuming your running the 12.7 drivers and beyond). I like the site that matto17secs linked because its one of the few that actually used the newer drivers from AMD.

    What I guess I'm getting at is pick a card and be happy.

    The sapphire card I have runs at stock speeds but I have done test runs with it at the 1100mhz(base 950) and memory at 1275(base 1250)mhz and it was amazing, however I chose not to run it there all the time. I fell like I could push the memory to 1300 easily but have felt no purpose to yet.

    Highest temp I've seen is 68c and that was after 4 hours of battlefield.
  5. Doesn't NVIDIA have that very efficient new way of doing AA though?

    The new Nvidia AA modes are FXAA and TXAA. FXAA can be forced through the control panel, while TXAA is so far only available on games that implement it into their code.

    Nvidia also has Adaptive VSync which will prevent unnecessary dips in framerate when VSync is enabled.

  7. So basically, it's faster and looks better? Do you think it is enough to offset the larger memory bandwidth of the 7950?

    All you have to do is look at the benchmarks and don't overanalyze.

  10. dude, if you want to OC, the 7950 is a much better card. the card OCs to better performance than even the 670 OC. TXAA and FXAA aren't all that great. FXAA blurrs the whole screen and makes the whole game look washed out. TXAA is only available in 1 game and thats about it, it still has some of the same problems as FXAA.
  11. keep in mind that his card is excessively long for a 6870 (11 inches) and its pretty dam loud

    fxaa is ok
  12. will 750W be enough for 2 overclocked 7950s and i5?

    yes. 7950s draw about 200W at max so theoretically your computer with 2 7950s will draw about 600W max when loaded with stress testing software.
  14. How about folding performance? I occasionally do F@H. I know CUDA is generally better, but is it enough to beat the 7950's superior compute power?

    There must be a reason Anandtech doesn't test AMD cards on Folding@Home. Possibly CUDA is a requirement?

    As far as I know F@H doesn't need cuda. Cuda does help a lot. The 660 ti should be much faster at F@H.
