The best I can do here in the USA is about $250 for a simple Windows 7 64-bit PC With 8GB DDR3 memory
I'm not excited, why do I need to calm down. I mentioned 8GB (2-4GB DDR3 modules) because it would still fit in the $250 category and it woks nicely with Windows 7 64-bit. I just built a PC for this price
Yes it is not a gaming PC, but the users are happy with it's on-line gaming capabilities. You can always add a low profile video card... I built my gaming PC as you see in my specs for $1200
You would be surprised at just how much a good low-profile video card can add to a lesser powerful slim-line computer
