I currently have a corsair vs650 PSU and my specs are: i5 3350p, sapphire 7950 OC Boost, asrock z77 pro3, 2*4Gb 1600mhz HyperX ram, a WD caviar black of 500Gb, a samsung HDD of 250Gb, a DVD and 5 fans including the CPU fan. Could my PSU handle another GPU? I appreciate any advice. :)

I am barely able to run my configuration on my 750w PC Power and cooling silver rated PSU. I actually had to reduce my CPU overclock to stop the random restarts. You have a CPU that uses quite a bit less power than my power hungry PH II x6, so a good 750w should be enough. If you plan to overclock anything/everything, you may want to look at a 850w quality unit such as this one: http://www.ncixus.com/products/?sku=63239
