"Wow mate, thanks for all that, enough info there to keep me busy for a while! Would I be right in thinking going for the 1333 memory would be the best bet so it's future proof if I upgrade the CPU, which looking at your suggestions I probably will. This is something I may well do as like you say there seems to be plenty of good options around at decent prices. I had got my eye on a NVIDIA Quadro FX 3800 but I'll give the 600 a good go before doing anything there. Good to know I can upgrade to USB 3, my camera uses that for shooting tethered. I went for the T3500 after nearly getting a i5 machine, reading up on it, it just seemed a better base for upgrades and probably cheaper than going the mainstream PC route."
Yosser,
The difference in RAM speed will not be too noticeable, but, yes, may as well have the faster one. There is a counterintuitive n inverse proportion of speed to latency- the higher the speed, the more latency. DDR4- 2133 has a latency of 15 while DDr3 1333 can have a latency of 8.
The Quadro FX 3800 is an exellent 2D GPU. On Passmark, the top 2D score in a non-overclcocked system is 912. In the FX (Fermi) series, athe FX x800's was the top line. I have an FX 4800 in a Precision T5400 and it was really very good. Some people stil use the FX 5800 as the GPU is 512-bit and there is 4GB memory.
In the all time best Quadro 2D's the winner is the Quadro 6000 which can have 2D scores over 1500. 3D is over 3500. That is a 384-bit card with 6GB- and was $3,900 new. Today, they're sold for under $400- but I think use about 240 W/
For a budget GPU, the Quadro K620 2GB is very good- sometimes sold used for only $100-120. On a Dell T3620 (Xeon e3-1240 v5) a K620 has a 2D score of 1069. The 3D is not too bad either- to about 2400. They're very low power - 45W- and the K620 would be my recommendation if the 600 is not shifting the pixels well enough.
Cheers,

PS: Here's a list I made of CPU choices for a T3500:
