which is best?

[Warlock]

Matrix infinity is the better of the two. This DMS chip is a so called solderless chip. It uses a clip to attach itself to the chip on the MB which can bend chip legs and damage the console. If you want to use a DMS series chip get it soldered in correctly. The DMS is also alot more fussy about the install compaired to the MI. If it was my money i would go with the MI or the Crystal chip 1.1
