Hi guys! I am 25 and have not kept up on computer specs like I once did! I actually took a computer repair class in high school so I know the basics. I am looking for a new pc to upgrade. This is the stock build that I am seeing at the moment. Processor: Intel Core i5-2320 processor(6MB Cache, 3.0GHz) Genuine Windows 7 Home Premium Inspiron 620 Minitower 500 GB SATA Hard Drive (7200 RPM) 500 GB SATA Hard Drive (7200 RPM) 8 GB Dual Channel DDR3 SDRAM at 1333MHz (2 DIMMs) 16X DVD +/- RW Drive 300 Watt power supply I am hoping to get a 1-2gb graphics card. Might I need to upgrade the power supply that comes with the computer?
