Judging by the desktop video card performance we can expect that the GTX 560M equipped notebooks will perform just a bit below the GTX 550Ti / Radeon HD 5770. With the GTX 570M notebook graphics cards you get gaming performance just a bit above the same cards.
You have to step up to the GTX 580M or Radeon HD 6990M to get performance above the desktop GTX 460 / HD 6850.
Looking for HD 6970 performance? You need to be looking at HD 6970M CrossfireX notebooks.
For around $1120 you can get a FORCE 1761 17" notebook
The compromises? It's a MSI chassis and a dual core 5-2430M 2.4Ghz CPU with GTX 570M graphics.
Includes 8GB RAM, 640GB 5400rpm HDD, 17.3" 1920x1080 LCD and Win7 Home Premium.
And a bit over $1500 for a Radeon HD 6990M equipped Sager NP 8170
2x GTX 560M SLI should be just a bit better than a single GTX 580M or desktop GTX 460M.
NVIDIA GeForce GTX 560M review if you look just to the right of the review you'll see a vertical list of GPUs ranked by performance. It's not the same as actual benchmarks but it's a broad guide to where various cards or CFX/SLI combos rank in relation to other options.
I suppose you're already considered and discarded the desktop gaming rig option?
Alienware mx18. claims to have a 460m SLI. I dont want to be ripped off, how can I confirm that the card is a NVIDIA GeForce GTX 460M SLI and not just the 460M. Per the benchmard page, there is a huge difference.
Yea myztery, that Laptop is GTX 460 SLI. and if you could even find one it stock for a good price, Get it. Cause other than ASUS this is your best option. the Republic of Gamers laptops is the best tho for the money
