[citation][nom]trandoanhung1991[/nom]Well, there certainly is a market for those. I wonder how many professionals actually run on gaming workstations because the same kind of power using professional cards are so much more expensive.[/citation]
It depends on the application. I've got a Dell 17" 1920 * 1200 I use for CAD work. It has an FX3700M in it, which was about a thousand dollar adder at the time, maybe 1500. For the software I use, It would blow away SLI 580's even today because the BIOS is crippled in the consumer cards. In some apps, the consumer cards are just fine.
Yes the dollars sound big, but think about the other costs. A top engineer or CAD driver is gonna run you 6 figures or close to it. The software on my machine is over 50k, plus over 10K a year in maintenance. The guy in the next office has WELL over 100k in software on his. If I can spend a few grand on a better laptop that gives a 5 to 10% increase, it's worth it. Kind of like tire prices on a Ferrari.
