I've had a sony vaio laptop for almost 4 years and i think it is time for me to get something new. But i really want to know what happened to this laptop and why it became so low. Last year and half (almost 2), i used to run black ops on this thing and grand theft auto IV and i've never had a single lag. It has now become so slow even after recovering it. My friends tell me that it is the fan. Well. i start off with 100+ fps the first 10 minutes in css or l4d 2. After that, my computer turns so bad and my fps drops to 10 and lower. The laptop gets heated so fast and you can't even touch the bottom because of how hot it gets. My computer specs are: Intel Core I3-330M Processor 2.13GHz Windows 7 Home Premium 64-bit Memore 4GB Ram ATI Mobility Radeon HD 5470 320 GB Hard Disk Drive It should be completely running fine with valve games and that's what it does the first 10 minutes. Is it the fan that is cauing less fps? Now, my other question is what i should get. I found this good tower at bestbuy with really good specs and they told me it would run any game even in the future. I need an opinion about it from you guys and if it can possibly run any heavy game like COD, Battlefield and other future games for years. If not, please provide me with any better gaming computer tower that can run any game better and is less then $1000 from bestbuy. Here is the tower i liked: http://www.bestbuy.com/site/Asus---...rive/7138076.p?id=1218831545767&skuId=7138076 By the way, is this upgradable?
