hmm not possible to upgrade PSU
already stretched my budget to max.
BTW if GTA IV lags in 9800, then Arma II would also have been lagged!!
BTW GTA IV lags in which settings!
5670/9800 cannot utilize full 1GB in 1440x900 right?
if yes, then XFX 512MB 5670 costs 6.7k, only 500 Rs more then 9800. But i think performance of 5670 is higher if you play Dirt 2 in dx10 settings!
