A 250Gb SSD should be ample, I’ve got a lot of add ons with my FSX install and it’s “only” 50Gb - you’d be going some to break 100gb imo.
As for your current cpu, a quick google shows it’s quite a bit slower than my old i7 870, given I got such a boost from my upgrade (I bought an i7 4790, 16Gb RAM and a motherboard to suit from the Members market here for ~ £250) I would expect yours to perhaps struggle a bit, but, it’s still a better chip than the designers ever envisaged so I’d certainly give it a try and see how it handles it.
Remember, FSX is all about smoothness of running rather than high fps rates- a we’ll optimised install will play just fine @30fps so long as you can maintain that frame rate,the last thing you want is an fps drop and stuttering whilst on final approach in a cross wind!
If you’ve got a spare hour or so, read and digest this....

An old but probably still one of if not the best FSX guides I’ve ever read- and I’ve read more than I care to recall!
Thanks for the reply Scania and the link to the "bible", I have not seen that one before so I will take a look and read it. Please forgive all the questions however as you have probably guessed I am new to building and upgrading PC's.
Have I misunderstood you re the SSD, I take it you are suggesting I leave my existing hard drive in place that contains Windows etc and then just add Steam, FSX and any add ons onto the SSD? If this is correct I can see when you say a 250 GB SSD would be ample, I could probably get away with a 125 GB model.
Thanks again.
