My work is considering getting me a Dell M6400 for mobile editing with Premiere and AE. I will be doing a lot of travel. Budgets are in the air right now so the mobile workstation my be out on the lower end of the range is the Dell Studio XPS 435 with the i7 core 920 and a 4000 series ATI GPU. Thoughts?

also the Dell m6400 comes with a mobile quadro 2700m 512mb.
