Maximum PC

Hi just joined the forums as im looking for a bit of computer advice

I am currently running a GA-G41MT-S2PT motherboard - http://www.gigabyte.com/products/product-page.aspx?pid=4061#sp

and have a Intel dual core E6600 (3.06GHz) and am using a nivida GT 220 graphics card. I am looking to upgrade my computer for more high end gaming, at the moment i am using the computer for Rift and PlanetSide but am playing planetside on the lowest grahics :/. Also i have 8Gb DDR3 RAM

I was interested in getting the GeForce GTX 650 Ti graphics card http://www.geforce.co.uk/hardware/desktop-gpus/geforce-gtx-650ti/specifications and I was wondering will my motherboard support it and if so will i need a new processor also and what would be a good case to hold it all . If you need any more information just ask

Thanks for all the help Im sure you will give.
