This is my current set up, it is cheap but has done well however i'd love to replace my video card.

CPU - AMD FX-6300 3.5Ghz 14MB cache,
Motherboard - ASUS MOTHERBOARD MODEL M5A78L-M,
Ram - 2 x 4GB 1600MHZ,
VGA - Saphire R7240 1GB DDR5,
PSU - 500W corsair

I would like to upgrade to a SAPPHIRE HD 7970 GHz Edition 3GB GDDR5 VAPOR-X.

The case dimensions are 187mm x 412mm x 409mm (W x H x D)

Any help would be greatly appreciated.
