if you are in london you should be able to get a much better internet connection than you have now, as yours is below the national average, you have worse internet than 3lionz!
your packet loss is atrocious, you should probably change ISP.
http://shop.virginmedia.com/check-your-postcode/ <- good ISP, enter your postcode to see what speeds you could get.
http://www.productsandservices.bt.c..._maxus_vidZ59_Broadband&vendorid=Z473&sissr=1 <-also good, (press "check speed" button & "i'm not a bt customer", then enter your postcode to see what speed internet you can get)
as for talking about your computer..... your CPU is okay(ish), but your graphics card will choke on legions (yes, i had one too) and will not run any modern games well (if at all).
it's time you probably got a new PC.
http://www.pcspecialist.co.uk/ <- these guys are good for cheap & well made custom PCs (including laptops)
http://www.dell.com/ Dell are also good if you want a no hassle computer, but as with most large pc makers, they have a habit of putting in a good processor and a poor graphics card for gaming.
don't go for a HP, their customer service is terrible, and they're also having an identity crisis.
if you need help in choosing a new pc, pop me a pm
