I saw the Accelero XTREME 4870X2 on Artic Cooing's site. Now, I, like quite a few people I'm sure, are rather concerned about the pretty intense operating temperatures of the 4870X2 (especially considering my country's hot climate). Also it seems a bit hard to tell if it's a dual or tri slot cooler, looks dual. I don't want to void my card warranty by removing its cooler, etc., but do you think this is a worthy investment? I have a CM Storm Sniper (default fans only). What do you guys think?
