Awh i wish you didn't order that OCZ StealthXstream , i have it and want to trade it in already for a better one. It does however come with 2 6-pin connectors(pcie) and 1 2 pin connector for extending a 6pin to an 8pin so don't worry about that 9800GTX at least. On CPU cooler i don't see why you shouldn't splash out on a thermalright ultra extreme.
