I'm thinking about buying a Dell Studio XPS 16 and want to be able to play crysis full everything at 1920x1080 resolution. Right now my settings for the computer are:Windows 7 64 bit OS, Intel® Core™ i7-820QM Quad Core Processor 1.73GHz (3.06GHz Turbo Mode, 8MB Cache),6GB Shared Dual Channel DDR3 at 1333MHz,Full HD Widescreen 15.6 inch WLED LCD (1920x1080),ATI Mobility RADEON® HD 4670 – 1GB. Will this run it? And don't tell me that the graphics card isn't good enough because I've seen this exact computer (except with 8 Gbs of RAM) run Crysis warhead on Full settings in full HD flawlessly on youtube(it's no longer on youtube because the author took it down for some reason). Also, do I require 6 GB of RAM or would 4GB suffice? Thanks in advance.
