Ok, had a look at the alienware laptop again and for £1347.72 its going to get me:
8800M GTX
2.4 Ghz processor
1 GB Memory
120gb 7200
so i'd then have to buy 4gb memory from crucial for £60 and then the HDD would cost £80 from Scan, so it may be best to upgrade the HDD with alienware, and the asus is cheaper in every way apart from it doesn't have the GTX. And i still think this is paying a lot for what i'm actually getting, isn't it?
So much better would this be in performance terms than the Asus or my current desktop? What i could do for this is go for the basic alienware setup and then upgrade later on.... How easy would it be for me to put the new ram and hdd in anyway?
