Guys I'm really confused by many many graphic cards available in market that which is better than other?
Should we purely go by the clock rate?? Like a card having core/memory clock of 500/1000 MHz is better than a card having clock 450/800 MHz.
But i've seen some cards having lower clock rate but still expensive than other. Like inno3d 8600gt ichill ddr3 which has higher clock but cheaper than inno3d 9600gso.
Secondly I can't understand the memory width thing like some cards are 64-bit some 128 bit, what i'm confused about that if a memory which has a higher frequency lets say 1.2GHz and 128 bit how it will compare with a card that has 1GHz and 256 bit. Coz the cards now days have bandwidth like 15Gbps, 20Gbps, 30, and so on so are todays games capabale of exhausting these cards with this much of bandwidth?
