Swap that SSD out for http://www.newegg.com/Product/Product.aspx?Item=N82E168... Definately! No debates. Better reliability, life expentency, and r/w speeds, and the IOPS crush that shitty Samsung. The only competition to Corsair was Mushkin or OCZ that is why samsung came out with the 840 series.
For the video card I would upgrade. The motherboard if $50 cheaper, the power supply is $30 cheaper, the SSD is $15 more, the HDD is $5 more, 80-20=60 saved to throw toward a 660/ti/70. Not to mention its better components.
