It is not unreasonable of me to buy a new PC that I really don't need so my sister can have mine is it?

Mine is a bit shite. I will need a new one within the next 2-3 years as this one is rapidly going out of date.

My sis has no PC at all. Mine does everything she will need it to, bar needing a card reader installed, which is cheap and easy.

While taking her round PC shops today I found a second hand custom built gaming rig selling for half the price it's worth. She could not afford it. I could.

I don't need a gaming rig I want one though, just so I have one and to make MNetting sooperfast or a new PC yet, but I've been fancying upgrading mine for a while and this works out cheaper than the motherboard/CPU bundles I'd been looking at.

It is my duty as a good sister to buy it isn't it?

Yes

Absolutely! I've had many a new thing for that same reason

Yes! She's lucky to have you

I did the same for my mum. :)

yes of course what a kind sister you are

If you can afford it and wanted it anyway, absolutely go for it! Have upgraded several bits over the years for similar reasons! :)

It also comes with a monitor that is better than mine.

I think I will have to go and buy it tomorrow.

Life would be very dull if people only bought what they needed. Do it!

Why don't you buy it for her instead?

Because I need it Smiles, it's eleventy billion times better than the one I have and almost as good as, but a fraction of the price of the one I have been building in my mind for months.

Mine is upgradable, with a newer CPU she could get a good few years from it.

When the iPhone 6 is released in September I'll be upgrading so my mum can have my iPhone 5s. What a wonderful daughter I am!

It would be rude not to

OP, it's bad form on MN to bring up posts from other threads, so I won't post details here, but I remember you had a pressing need to move and were saving to do so (the dogs were a priority, right?)

If you've managed that, and can afford the new PC, go for it. If not, get your priorities right.

D0oinMeCleanin - Having read TheBossOfMe's post followed by a couple of your other threads I would like to revoke my previous message.
I don't think it is sound advice to encourage you to spend money that you don't need to as your previous threads suggest financial difficulty and a lack of money management.
I think you need to write down everything you are spending and make sure that you can afford them. I agree with TheBossOfMe - priorties should be looked at here, if you're hoping to move out of the council house then spending money you don't need to is going to harm you in the long run
