Need help comparing computers

[Edeslash]

Hello! I'm planning on buying a new computer as a local store's own package. Could you help me compare these products? The sites are in Finnish but you can see the parts.

For how long can I run games on high settings with these ones? Are there big differences between them? Would you change any particular parts?
Here are some of my options:

http://www.lapstore.fi/product_info.php?cPath=56_10&products_id=30581

This one's a lot more expensive, is there a great difference in comparison to the other two? http://www.lapstore.fi/product_info.php?cPath=56_10&products_id=44254

The Intel machine has a better gaming processor and video card but less RAM(I'd wand 8GB for that build). That Intel build looks pretty old as it has lots of 'older' hardware.

This one would be the best buy in my opinion: http://www.lapstore.fi/product_info.php?cPath=56_10&products_id=44252
The only thing I might change about this(depending on your needs) would be to get a slightly faster card like the 6950 or GTX570. It's great how it is though.


And that more expensive one has a beast of a video card and SSD which would be fun if you had it but not necessary if you're on a budget.
