Portal 2

Portal 2 continues the long and proud tradition of Valve’s in-house Source engine. While Source continues to be a DX9 engine, Valve has continued to upgrade it over the years to improve its quality, and combined with their choice of style you’d have a hard time telling it’s over 7 years old at this point. Consequently Portal 2’s performance does get rather high on high-end cards, but we have ways of fixing that…

Portal 2 ends up being at about the middle of the road as far as performance goes. The 7870 enjoys a smaller lead over both the 6970 and the GTX 570, while the 7850 takes one of its biggest losses versus the 6950 and GTX 560 Ti at around 3-5%. The good news is that at these performance levels, performance is good enough for the SSAA bonus round, which sees the 7870 hitting just shy of 60fps. The 7850 on the other hand only falls further behind the GTX 560 Ti with SSAA, and at 45fps probably isn’t going to be quite fast enough to make the cut.

    Yeah, I'm trying to figure out if a 7850 could go in an Alienware X51. It looks like it uses a 6 pin power connector and puts out 150W of heat.

    While we would lose Optimus, would it work?

    optimus is laptops only. You do not have optimus with your desktop. Reply

    The X51 has desktop Optimus.

    "The icing on the graphics cake is that the X51 is the first instance of desktop Optimus we've seen. That's right: you can actually plug your monitor into the IGP's HDMI port and the tower will power down the GPU when it's not in use. This implementation functions just like the notebook version does, and it's a welcome addition."

    In reality, if I owned an X51, I would wait so I could shove the biggest 150W Kepler GPU in there for some real gaming.

    But I'm sure the X51 will be updated for Kepler and Ivy Bridge, so now wouldn't be the best time to get an X51.

    Waiting games are lame...

    Wrong. Read a review.....The bigger issue will be the orientation of the PCIe Power Connector I expect. I have a tightly spaced HTPC that currently uses a GTX 570 HD from EVGA because it was the best card I could fit in the Antec Fusion enclosure. If the PCIe power plugs were facing out the side of the card and not the back I would have not been able to use it. I expect the same consideration will apply to the even smaller X51 Reply

    he does. x51 is a desktop with optimus.

    EA really screwed AMD over with Battlefield 3. There's basically no reason to consider a Radeon card if you plan on heavily playing BF3, especially since most other games like Skyrim, Star Wars, Rage, etc, all run excellent on any $200+ card, with anything $300+ being simply overkill.

    The obvious best card for Battlefield 3 is a Geforce GTX 560 TI 448 Cores for $250-$280, basically identical in performance to the GTX570 in BF3. Even those on a budget would be better served with a low-end GTX560 series card unless you run resolutions above 1920x1200.

    If I were AMD, I'd concentrate on increasing Battlefield 3 performance with driver tweaks, because it's obvious their architecture is superior to nVidia's, but these 'exclusive' titles are tainted.

    screwed how? only the 7850 is slightly lagging behind, & historically BC2 was consistently a little faster on nv

    also BF3 has a large consistent boost since feb14 drivers (there was another boost sometime in december, benchmark3d should have the info for both)

    @ Samus

    BF3 isn't an Nvidia "exclusive", they made sure to remain vendor agnostic and participate in both IHV's vendor programs. No pointing the finger and crying foul on this game, it just runs better on Nvidia hardware but I do agree it should be running better than it does on this new gen of AMD hardware.

    In the reviews here SHOGUN 2 total war is said to be the very hardest on hardware, and Nvidia wins that - all the way to the top.
    --
    So on the most difficult game, Nvidia wins.
    Certainly other factors are at play on these amd favored games like C1 and M2033 and other amd optimized games.
    --
    Once again, on the MOST DIFFICULT to render Nvidia has won.
