The other option(for new genaration) is hd4870 1gb/512mb.
@price performance 4850/4850 crossfire will be better.
You r using p4 3.2ghz @3.6ghz. What is your computer's motherboard model/chipset model. My old 9600gso ddr3 oc was bottlenecked by p4
[email protected] at 1024*768(Anik's previous rig who is the owner of the card). After upgrading to pentium dual core
[email protected] every game is running very good(Anik is very happy). Even at 1440*900 res. Hd4850 will be bottlenecked much. As u r upgrading soon it's ok.
Lower cpu related option to medium or low in game setting and use AA and AF for better image quallity. 3.2ghz p4 can be overclocked 4ghz+ easily and it's now winter(temp should be below 70`c with stock coolar).
