Ahoy!
Can't
help you with a shop, but for that money you should be able to buy a 1GB RAM, fast dedicated GFX card and core2 CPU. Compare a few screens and you'll be fine
I'm still playing on a 1,7GHZ, no dedicated GFX card and 512MB RAM IBM Thinkpad

I can regulary take a shower before if loads, LOL :rotfl:
