Yup looks like im going with the 128GB vertex 4, thanks for your help spirit!
Cant wait till christmas now!
Thats for the input laquer, helped to make me decide on getting one!
But also a note on the vertex 4, it has 512-1024mb of DDR3 RAM, built in, so even when full, it can still perform well and instead of getting less than 128GB I will actually get 128gb! A nice little perk, could go in to detail but anyway im happy with it, and it has a 5 year warranty so hopefully thatll be enough! I can always expand if needed.
