    Isnt Crossfire a bit finicky anyway? You know your probably ok right now. I bet you could get away with just a video card until Haswell comes out. I doubt it will be much of a performance gain, but it will be a new socket and you will be future proofed a bit.

    Honestly I would do this. The i7-920 IMO is still plenty powerful, get a new video card and be done with it.

    Granted, I haven't been as performance picky nowadays as I used to be, so it could be that talking, but dropping serious coin when you already have a 920? I dunno, that doesn't seem worth it to me.

    Even if you board isn't playing nice, get a new board or a used one from the AT FS/FT forums, new video card, and be done until haswell or later.

    One concerning thing about getting a new video card is the power supply I currently have.

    It's a Rosewill BRONZE RBR750-M at 750W
    http://www.newegg.com/Product/Produc...82E16817182186

    The concerning thing is the amperage - it has +12V at only 18A. While I was troubleshooting my 660 TI (which turned out to be some bad compatibility between the DX58SO motherboard and the MSI brand of the card), I noticed that the card had a minimum requirement of +12V at 28A.

    Looking at a couple manufacturers' pages, I can't find a 660 TI that would be happy at 18A.

    You are just looking at the #1 12V rail. That PSU has four 12v rails, with a combined rating of 54A. It shouldn't be a problem at all with your system even with a GPU upgrade.

    Ah, I didn't know you could add them like that. Thanks

    You can't add them directly, but you can figure it out by looking at the label on the PSU, which should give a combined rating, as it does in the picture on the Newegg website.

    In theory, if you have a system running at very close to max, you could have an issue with load balancing on the rails, but you won't with your system.

    Alright, I think I'm going to just get a new video card now, and look at another upgrade in about 6 months or so. It sounds like the video card will relieve my PC of a lot of the stress I'm seeing right now.

    Thanks for all the info everybody. I'm going to read some more on Haswell.

    Sounds like a smart plan, Siyko. Besides, if you upgrade the video card now, its not like you can't use that video card in your new setup. I don't think your proc is hurting you enough now to justify it...do video now, everything else later.

    Crossfire/SLI can be quite finicky. You got that right... :D

    Much easier to just use a single GPU.

    Can't seem to find that particular thread. Bad luck I guess.

    Your issues have nothing to do with AMD versus Nvidia and everything to do with trying to Crossfire two low-end cards. You'd have the same types of problems if you tried to SLI two GTS 450's.

    Overall, I'd say that you have a tendency to severely under-spec your GPUs. You mentioned that you thought that buying an $800 PC and adding $1000 worth of GPUs wasn't a smart smart way to build a gaming rig. In reality, that ratio is not too far off from what you want. To illustrate, here's a system:

    i5 3570K $215
    ASRock Z77 Extreme4 $128
    Crucial DDR3 1600 8GB $35
    GTX 670 4GB SLI $800 AR
    Plextor M5S 128GB $108
    Samsung F3 1TB $65 AP
    Lite-ON DVD Burner $18
    Rosewill Capstone 650W $80 AR
    Fractal Design R4 $90
    Phanteks PH-TC12DX $60
    Total: $1599 AR AP

    This config spends $800 on the GPUs and $799 on everything else (1:1 ratio). It will completely demolish the i7 3930K + GTX 660 Ti rig that was posted earlier. "Not in the same league" doesn't even begin to describe the difference in gaming performance.

    So now you not only have a good gaming config to work off of, but more importantly you understand that your thinking was going down the wrong path before. :)

    Interesting. I didn't expect that at all - thanks for the information.

    However, the problems I'm referring to with ATI vs Nvidia are not power issues - they are driver/software issues. With crossfire enabled, some games don't render some objects, or don't load some textures, or don't work, or anything. I often have to disable crossfire.

    Additionally, I get some ATI issues when I drag rendered objects between monitors - I often get a flicker or some artifacts when I do so.

    It's true I haven't tested this on SLI NVIDIA cards, but I don't get any of these issues on a single NVIDIA card.

    That's exactly what I did - I bought a Gigabyte 660 TI and returned the MSI =)

    I've never run a dual-GPU system and I probably never will.

    I have bought multiple GPUs from NVidia and AMD/ATI, done my homework beforehand, and been satisfied with every single one.

    Comparing one company's dual-GPU issues to another company's single-card setup isn't really meaningful, not to mention that whatever issues you had with dual 5xxx cards, they're almost 3 generations old now.

    That's exactly the issue mfenn is talking about: driver/software issues (and he goes on to address the more effective means of building a gaming PC, but I digress). Both Crossfire and SLI have issues in the drivers and in microstuttering--Nvidia is typically a little better for multi-GPU combos, but it's best to avoid it all together unless you are going crazy at the high end.

    AMD is a much better buy right now at the higher end: the 7970 performs better than the 670, and can overclock to be on par or better than (depending on your luck) a 680, and the 7970 comes with 3GB of memory for as low as $370 USD, wheras you'd have to go over $400 to find a 4GB 670 card from Nvidia (the memory is important for things like modding game graphics like Skyrim and Crysis as well as anti-aliasing.) On the other hand, memory is generally not an issue at 1080p and even 1440p. Multi-monitor setups, on the other hand, will probably need it.

    TL;DR: AMD is better at the high end (the 660ti is particularly bad due to a crippled memory buswidth).

    :thumbsup: Thanks for expanding on the point that I was trying to get across. :)
