I have only just started to browse the pcspecialist site seriously with a view to upgrading my ailing computer and have been very impressed with its layout and ease of use BUT two additional features would seem to be worth suggesting.
(1) As you customise one of the basic models, it would be VERY handy to have the cost updated as you go. As far as I can see, you have to wait to go through the compatability test before you see how much you're about to spend. Maybe there's a way to switch this function on as an option, but if so, I haven't found it. After all, most of us work with these annoying things called budgets.
(2) I was pleased to see that after experimenting with a couple of customising changes, there was an automatic compatability test. But what happens if you specify something that isn't compatabile? Is there an immediate and automatic flag? If not - there needs to be.
Beyond those two initial niggles, I must say that even though I'm very experienced as a PC user, I've never had time nor cause to delve into the realms of technobabble and the pcspecialist site seems to be remarkably friendly as regards providing lots of help when needed.
Added to which, of course, I'm a retired old fogey with a gradually addling brain.
