Need advice for buying new HP laptop.

I am thinking I may need to buy a new laptop with bigger hard drive, more memory, faster processor. The specs on current laptop are:
HP G60 Notebook, 16.9 screen; Processor - Pentium (R) Dual-Core T4400 @2.20 GHz; 4.00 Memory; Windows 7 64 Bit Operating System.

The one I am looking at is : HP Pavilion 15t-n200; Operating system - Windows 7 Home Premium 64;
Processor and Graphics 4th generation Intel® Core™ i5-4200U Processor + Intel® HD Graphics
Display 15.6-inch diagonal HD BrightView LED-backlit Display (1366x768)
Memory 12GB DDR3 System Memory (2 Dimm) (or) 8GB DDR3 System Memory (1 Dimm)
Hard drive 1TB 5400 rpm Hard Drive (or) 750GB 5400 rpm Hard Drive

My goal is a faster computer. Any advice/suggestions?
