Below are the three graphics cards I'm looking at.

My first question is what's better higher mhz? Or better and larger memory?

The second is can I overclock using just fans? Which one of these is best without overclocking and with ocing? I'm getting a coolermaster with 4 80mm fans.

It will be used for my digital camcorder, video editing, and ofcourse a game or two.




nvida 6600gt 128mb GDDR3/1000mhz corespeed 500mhz

x600xt 256mb ddr/740mhz core speed 500mhz

x700pro 256mb GDDR3/860mhz core speed 420mhz

PS. third question Should I be getting a 256 bit instead of a 128 bit? Anyone know where I can for around $200.00???
