Conclusion: NVIDIA Retains Their Title, But Barely

We had a hunch that NVIDIA's GeForce GTX 580M would continue to be the fastest single GPU available in notebooks, and that turned out to be accurate...mostly. In a couple of games the 580M is a slam dunk, while in others it trades blows with AMD's Radeon HD 6990M. Once multi-GPU solutions are brought into the equation, things tend to veer more in favor of NVIDIA's solution, but we remind you that two isn't always better than one: it may look better on charts, but benchmarks don't tell the stories of micro-stuttering and sometimes inconsistent performance. There's a reason none of our editors would recommend a multi-GPU solution in a desktop, and so I personally can't really recommend it in a notebook either.

What are we left with? Well, once again my recommendation at the end of the first part of the M18x review applies: the M18x feels like too much, especially compared to the M17x R3. That's doubly true when you realize the M18x's only single-GPU solution is a GTX 560M; everything else is SLI or CrossFire. So when you bounce down to the M17x R3, you can get a single 6870M, GTX 560M, 6990M, or GTX 580M, and unfortunately for NVIDIA, this is where AMD steals the show.

Simply put, the 580M just isn't worth the $300 premium over the 6990M. The two are comparable enough that situations where NVIDIA's part leads just don't justify the massive difference in price. Those of you still itching to configure an M18x will have an even easier time with it: a pair of GTX 580Ms is a staggering $700 more than a pair of 6990Ms. If price is of no consequence to you then by all means go for NVIDIA's solution, but if it matters even in the slightest, AMD wins the value competition hands down. Think it's just Alienware? A visit over to AVADirect reveals the same kind of price difference in a custom configured X7200.

Ultimately both of these solutions are more than adequate for getting your mobile game on, but AMD really does win the value proposition by a landslide. The GTX 580M is a fantastic GPU and I've certainly gotten a lot of mileage out of mine, but I also need the support for CUDA. If you don't, your answer is a simple one, and the M17x R3 with a Radeon HD 6990M may just wind up being the best balance of price and performance for mobile gamers. The M18x remains, as before, too much for most users.

    Would it be possible to make the Radeon bars red and the Nvidia bars green in your charts? It's pretty minor, but it messes up my ease of reading knowing these companies have their colors. Reply

    Nvidia's pricing of the GTX 580M is ridiculous. Reply

    Yeah, it was what kept me from pulling the trigger for a while on the m17x... i wanted the 120hz screen and they wont sell it with the 6990 (I dont care about 3d).

    Dell is selling the model with 120hz screen for 300 bucks less now though.. so I went ahead and ordered one finally after considering the m18x and m17x.

    It kinda sucks that the system that would be able to take advantage of a 120hz screen the most (m18x w/ SLI) doesnt have it as an option.

    This is exactly what I had been wanting to see. As far as comparing the m17 to the m18, another difference is the reduction in the pixel density. I don't understand why Alienware would put this monitor in this laptop.

    Anyway, thank you again.

    The one thing that 580M stands out from the 6990 is their Overclocking capabilities, I've seen what the guys are doing in NBR M18x Forums and it's simply destroying AMD due to the fact that the Nvidia's BIOS is flashable and currently we've seen up to 35% Overclock! that's pretty crazy! It can achieve that due to the Video BIOS and the ability to be able to leverage higher voltage.

    That's where the extra 300 goes ;) (Remember this isn't a consumer type system, it's 100% enthusiasts)

    Righ now, the M18x with 2920/2960 and 580M SLI Setup with Mod BIOS makes for the fastest laptop in the planet, ahead of Clevos with Desktop CPU!

    Good overclocks, just a shame the card is throttling itself. Reply
