Thanks for the replies so far.
Looking for around £1500ish, the cheaper the better of course.
I was thinking as much RAM as possible and a quality processor.. graphics card and a SSD drive were unncessary?
Thanks!
Thanks for information, I had no idea 32-bit Excel was limited to 2GB RAM.
Will be upgrading to 64-bit on my current PC immediately, I have however also got a Mac which is running 64-bit and it doesnt have struggle just trying to open the spreadsheets.
So the consensus is, stacks of RAM, SSD and a solid processor? Oh and 64-bit Excel!
Thanks guys.
