I currently have a computer I built in 2008 (Intel Q9450, 4GB DDR2, GTX 260, Samsung 830 128GB SSD) it still performs reasonably well but a few things are making me consider doing a new build. The GFX card is going faulty, I want a smaller case, front USB3 ports, more RAM and a larger SSD... I could upgrade/fix these on the existing build, but it would only cost about £300-350 extra to do a complete new build.
It's used for development (work), animation (hobby) and light gaming. One of my main concerns is I need it to be as quiet as possible, these are the parts I was thinking so far:

note: I know the SSD has slower write speeds (~260MB/s) but I've had such bad experiences with the OCZ Vertex 3 / OCZ Agility 4 both at home and at work I wouldn't touch them again, and others are quite a bit more expensive.
Would it be a worthwhile upgrade over what I have already, or should I just upgrade/fix the old build? Are there any parts you would change in the new the build?
Thanks in advance.
