hi...soon im going to buy a gaming laptop, alienware m17x10 with intel i7 720m, 4gb ram, 500gb HD and dual ati radeon 5870 with 1400x900 res, im just wondering if the updates for ati are consisted compared to nvidia, so far i havent heard of a gaming laptop with a nvidia gtx 480m (i heard only 460m), im a hardcore gamer and wants good performance regardless of price, also another choice of mine is the asus G73, with intel i7 720m, 8gb ram, 1T HD and single ati 5870 but with a 1920x1080 resolution...both of them 17 inches size...please help me about the pros and cons about the two, and your own opinion of which is the best one, dont mention the price difference because it doesnt matter, its about the performance of these two laptops that is in between my choices. Thanks in advance!
