I just got a standard chaintech fx5700 (125$) and I think I can do a bit better with the speeds. The card has a heat sink over the gpu front and back but nothing on the hynix memory modules. Has anyone heard how good the card and memory does on overclocking? The main point of the post is to ask where I can get some ram sinks. compusa and fry's failed me. I want the kind I can apoxy onto it.
