Performance issues on a good computer

When looking at these different cards nevermind the memory if it says 3GB that is somewhat important but look at how many cores are available or stream processors...

 

GT 620 cores=96

GT 620 MHZ=700

 

GT 640 cores=384 (for the DDR5 model)

GT 640 MHZ=950

 

GTX 780 cores=2304

GTX 780 MHZ=900 I got mine OC to 1050

 

 

I am not sure on the specs of Radeons as I strictly purchase NVidia but there you go...

 

more cores equate to more GPU computing power but also they need more wattage like an 850 or higher PSU....

 

a GT 640 is lower range sorry......basically an entry level GPU from Nvidia

When I got my computer that was actually pretty good. I haven't had the money to buy a new one.
