I am going to get a 7900GS for a build i will be doing. I need help deciding what brand to go with, but the LeadTek WinFast 7900GS has a fan that covers all the RAM, and all the other ones that are 199.99 dont. I wondering ifLeadTek is a good brand. Or if theres another 7900GS thats a good brand and covers all the RAM w/ the heatsink. Thanks.
