i am lookin gto spend under 2500. I can build an alienware laptop with dual 4850s for under 2300. I was just wondering if the performance is any good, or if it is just a ripoff. Also do alienware laptops overheat.
I think out of the ones you have listed the 260m SLI is the best however the mobile radeon 4850 in cross fire will be close, the 280m consumes less power and generates less heat but is not as good as the first two options. Alienware laptops are usually very well built although their customer service is horrible, depending on the intensity of what you wll be doing i dont think you will have issues with heat if gaming is your main thing then you are good to go and you can always buy a laptop cooler later on they dont cost too much, anyways i have a chart with various mobile graphics cards benchmarked to help you out as
Are the drivers for crossfire good in laptops. And from what i am gathering i will not overheat playing Cod4, crysis, warhead, cod5, empire total war and spore. And can i hook up my 24 inch screen to the laptop so i can game on it
Can those laptops perform nearly as well as sli gtx 275 with core i7 920
the mobile versions of those cards you usually perform somewhere close to the desktop gtx 260 processor wise you should be able to get alienwares with much better frequency than 2.0 ghz and if gaming is your concern then you should go for that. Only go quad if the processor speed is decent otherwise stick to dual for laptops....no laptop would perform close to an i7 rig with a gtx275 thats asking for a lot
