well basically I just try all games . my config is AMD3000+, 1gb ram, MSI rs482-ILD mobo , zebronics cabinet , ok . I heard the price of 6600 gt has decresed to 6k . is that true ? i AM thinking of buying 6600 gt or ATI equvalent of 6600 gt . Basically which card is the ATI 's equivalent to nvidia's 6600 gt ? should I go for that or I should buy nvidia 6600 GT ? and with my config how much performance increse I should expect ? right now I can play FEAR , DOOM 3 and oblivion ( sluggish ) . but if I attact a good graphics card can I play all the latest game still date ???
