Hello friends I have been using a laptop from last 3 years. performance of the laptop is very good. This laptop consists of Intel core i3 processor 2.30ghz and Intel hm65 chooser. It has 3mb cache memory which makes it to perform good. Pretty installed ram is 2 GB ddr3 but I expended it to 4gb . Now it works very fast. There is no problem in multiprocessing. It had 320 gigs of HDD. Which can be extended by the user. It is a good laptop for gamers coz it’s has nvidia geforce 410 GPU. Dedicated video memory is 512 mb ddr3 3. Display size is also big. it has 15.5 inch display. Video quality is also very good. Battery back up is also good. Battery gives the backup approx 4-5 hours which is more than enough. You can watch a full movie after full charging. This is good. I am very happy with Sony Vaio for this laptop. Performance is very good. And processor speed is also good. I have not faced any problem after buying this laptop. It has built in wifi, Bluetooth, 4 high speed USB ports. Memory card slots etc. This is budget laptop by Sony. Thanks.
