Compare options for New PC :)

for online gaming - and for personal games like PrinceOfPersia - 2t2, WW etc
which need 256 mb nvidia geforce cards as they say in their setups.
Please compare and tell me Your List of best possible parts
1. Best posible suggestion forum - VERY FIRST POST - chotocheeta

2. *h10010.www1.hp.com/wwpc/in/en/ho/WF25a/1090261-1111625-1116609-1116609-1116609-80627752.html
- 3rd one with 70k or second one with 50k+

3. Dell XPS 420 or 630 ( I guess 630 not avail in India, their India site shows only 420 ) and Similar ones...
my budget is upto 60 - 70 k but no issue for 'value for Mny' and
performance [ the more i can get like quad processor etc. , is better ]
[ the sites like npithub dont show all avail options in their PC calculator]
