    I built a computer way back in January, and I should be able to get high-ultra settings in 1080p on most of my games. My friend has almost the exact same PC as me (4GB less RAM, same GPU, different MB/CPU) but I lag a lot on higher settings. I updated my drivers and everything, anybody able to tell me what's wrong?

    The parts I used:
    Sapphire Radeon HD 6770 http://www.newegg.com/Product/Produc...82E16814102940
    XFX Radeon HD 6770 (Connected to above with Crossfire) http://www.amazon.com/XFX-Radeon-677.../dp/B005C31FJU
    ASUS M4A88TD-V http://www.newegg.com/Product/Produc...82E16813131646
    AMD Athlon II X4 640 http://www.newegg.com/Product/Produc...82E16819103871
    Rosewill HIVE 650 http://www.newegg.com/Product/Produc...82E16817182132

    I do not know what model/brand my RAM, HDD, or Optical Drive are. I didn't buy them.

    I can't run games on higher settings. Doing so will result in terrible stuttering.

    You said your friend had a different Motherboard and CPU.
    Do you know what CPU he has?

    Some i3. It's a dual core with 3.1 GHz instead of 3.0

    Battlefield 3 on Ultra is just a case of low FPS, but Skyrim lags like a bitch.

    The Intel i3 far outstrips your CPU in performance.

    Even if that might be so, I should technically be able to pull off high-ultra settings with this set-up.
    This could be dxdiag being a piece of shit, but instead of 2048 MB of RAM, I only have 1748. And the clock speeds of my second GPU sink down to 2D levels when in Crossfire use.

    If you're using a 32 bit OS, it makes sense. Windows doesn't use PAE, so you have a 4 GB memory window shared by all memory mapped devices in the system.

    Your two GPUs eat 2 GB of that memory window, leaving 2 GB. And it looks like your motherboard eats another 300 MB for motherboard resources (bus controllers, RTC, sound, network, USB, SATA, PCIe/PCI slots, etc.)

    Download it and tell us your temps. Could be you need to reapply your thermal paste or it was a bad application the first time.
