i'm thinkin bout getting a 4200 128mb with VIVO... getting all the bells and whistles. those 3 brands are the cheapest, especially prolink and aopen. but i tried my hardest to find a review on either one and i can't find anything at all. wanna know if there were any issues with any of these, what speed memory they have (4ns or otherwise), and overclockability. anyone know anything? or maybe i'll just get a 4600 VIVO for like $60 more.
