I think the 435, 455 or 720BE would be your best bet. I would prefer the 720BE.
For the card HD6670 should be the best option. Also the GTS450 (should stretch your budget a little though).
I am looking at prices from a dollars perspective, so see if the 720BE and the HD6670 fits your budget of 100-120 Euros.
Even then you wont be able to game hardcore on it though!
The GT220 is hardly card to do anything. Its best for FreeCell and Solitaire.
Final option is to wait and save and then get a mean one.
HD6670 is express 2.1, can I put it on my motherboard?? I don't play rpg game etc I want it only for nba 2k11 and pes2011, i think gt220 is perfect for me...
